VAR-201808-1002

Vulnerability from variot - Updated: 2025-12-22 23:39

Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. An input validation error vulnerability exists in the Linux kernel version 4.9+. The appliance is available to download as an OVA file from the Customer Portal. (CVE-2018-11506)

Wen Xu discovered that the ext4 file system implementation in the Linux kernel did not properly initialize the crc32c checksum driver. (CVE-2018-1094)

The inode_init_owner function in fs/inode.c in the Linux kernel through 4.17.4 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID. An OOPS may occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp. (CVE-2018-5390)

Security Fix(es):

  • Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. 6.4) - x86_64

  • ========================================================================= Ubuntu Security Notice USN-3742-2 August 14, 2018

linux-lts-trusty vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 12.04 ESM

Summary:

Several security issues were fixed in the Linux kernel. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 for Ubuntu 12.04 ESM.

It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS). (CVE-2018-3646)

It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). (CVE-2018-3620)

Andrey Konovalov discovered an out-of-bounds read in the POSIX timers subsystem in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. A remote attacker could use this to cause a denial of service. A remote attacker could use this to cause a denial of service. (CVE-2018-5391)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04 ESM: linux-image-3.13.0-155-generic 3.13.0-155.206~precise1 linux-image-3.13.0-155-generic-lpae 3.13.0-155.206~precise1 linux-image-generic-lpae-lts-trusty 3.13.0.155.145 linux-image-generic-lts-trusty 3.13.0.155.145

Please note that the recommended mitigation for CVE-2018-3646 involves updating processor microcode in addition to updating the kernel; however, the kernel includes a fallback for processors that have not received microcode updates.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

For the stable distribution (stretch), these problems have been fixed in version 4.9.110-3+deb9u1. This update includes fixes for several regressions in the latest point release.

Bug Fix(es):

  • After updating the system to prevent the L1 Terminal Fault (L1TF) vulnerability, only one thread was detected on systems that offer processing of two threads on a single processor core. With this update, the "__max_smt_threads()" function has been fixed. (BZ#1625334)

  • Previously, a kernel panic occurred when the kernel tried to make an out of bound access to the array that describes the L1 Terminal Fault (L1TF) mitigation state on systems without Extended Page Tables (EPT) support. This update extends the array of mitigation states to cover all the states, which effectively prevents out of bound array access. Also, this update enables rejecting invalid, irrelevant values, that might be erroneously provided by the userspace. (BZ#1629633)

Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2018:2785-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:2785 Issue date: 2018-09-25 CVE Names: CVE-2018-5390 CVE-2018-5391 CVE-2018-10675 ==================================================================== 1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.3 Extended Update Support.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

  1. Relevant releases/architectures:

Red Hat Enterprise Linux ComputeNode EUS (v. 7.3) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.3) - x86_64 Red Hat Enterprise Linux Server EUS (v. 7.3) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 7.3) - ppc64, ppc64le, x86_64

  1. Description:

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390)

  • A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system. (CVE-2018-5391)

  • kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact (CVE-2018-10675)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank Juha-Matti Tilli (Aalto University - Department of Communications and Networking and Nokia Bell Labs) for reporting CVE-2018-5390 and CVE-2018-5391.

Bug Fix(es):

  • On systems running Red Hat Enterprise Linux 7 with Red Hat OpenShift Container Platform 3.5, a node sometimes got into "NodeNotReady" state after a CPU softlockup. Consequently, the node was not available. This update fixes an irq latency source in memory compaction. As a result, nodes no longer get into "NodeNotReady" state under the described circumstances. (BZ#1596281)

  • Previously, the kernel source code was missing support to report the Speculative Store Bypass Disable (SSBD) vulnerability status on IBM Power Systems and the little-endian variants of IBM Power Systems. As a consequence, the /sys/devices/system/cpu/vulnerabilities/spec_store_bypass file incorrectly reported "Not affected" on both CPU architectures. This fix updates the kernel source code to properly report the SSBD status either as "Vulnerable" or "Mitigation: Kernel entry/exit barrier (TYPE)" where TYPE is one of "eieio", "hwsync", "fallback", or "unknown". (BZ#1612351)

  • The hypervisors of Red Hat Enterprise Linux 7 virtual machines (VMs) in certain circumstances mishandled the microcode update in the kernel. As a consequence, the VMs sometimes became unresponsive when booting. This update applies an upstream patch to avoid early microcode update when running under a hypervisor. As a result, kernel hangs no longer occur in the described scenario. (BZ#1618388)

  • Solution:

For details on how to apply this update, which includes the changes described in this advisory, refer to:

This vulnerability is also known as L1 Terminal Fault (L1TF). A local\nattacker in a guest virtual machine could use this to expose sensitive\ninformation (memory from other guests or the host OS). (CVE-2018-3646)\n\nIt was discovered that memory present in the L1 data cache of an Intel CPU\ncore may be exposed to a malicious process that is executing on the CPU\ncore. This vulnerability is also known as L1 Terminal Fault (L1TF). (CVE-2018-3620)\n\nAndrey Konovalov discovered an out-of-bounds read in the POSIX timers\nsubsystem in the Linux kernel. A local attacker could use this to cause a\ndenial of service (system crash) or expose sensitive information. A remote attacker could use this to cause a\ndenial of service. A remote attacker could use this to\ncause a denial of service. (CVE-2018-5391)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 12.04 ESM:\n  linux-image-3.13.0-155-generic  3.13.0-155.206~precise1\n  linux-image-3.13.0-155-generic-lpae  3.13.0-155.206~precise1\n  linux-image-generic-lpae-lts-trusty  3.13.0.155.145\n  linux-image-generic-lts-trusty  3.13.0.155.145\n\nPlease note that the recommended mitigation for CVE-2018-3646 involves\nupdating processor microcode in addition to updating the kernel;\nhowever, the kernel includes a fallback for processors that have not\nreceived microcode updates. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. \n\nFor the stable distribution (stretch), these problems have been fixed in\nversion 4.9.110-3+deb9u1. This update includes fixes for several\nregressions in the latest point release. \n\nFor the detailed security status of linux please refer to its security\ntracker page at:\nhttps://security-tracker.debian.org/tracker/linux\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nI62eV7vx701dQDjtcDy/yZlGDjFTULQkyX8GPL9hIBeRjCFRhrA=\n=h8it\n-----END PGP SIGNATURE-----\n. 6.6) - noarch, x86_64\n\n3. \n\nBug Fix(es):\n\n* After updating the system to prevent the L1 Terminal Fault (L1TF)\nvulnerability, only one thread was detected on systems that offer\nprocessing of two threads on a single processor core. With this update, the\n\"__max_smt_threads()\" function has been fixed. (BZ#1625334)\n\n* Previously, a kernel panic occurred when the kernel tried to make an out\nof bound access to the array that describes the L1 Terminal Fault (L1TF)\nmitigation state on systems without Extended Page Tables (EPT) support. \nThis update extends the array of mitigation states to cover all the states,\nwhich effectively prevents out of bound array access. Also, this update\nenables rejecting invalid, irrelevant values, that might be erroneously\nprovided by the userspace.

Summary:\n\nAn update for kernel is now available for Red Hat Enterprise Linux 7.3\nExtended Update Support. \n\nRed Hat Product Security has rated this update as having a security impact\nof Important. A Common Vulnerability Scoring System (CVSS) base score,\nwhich gives a detailed severity rating, is available for each vulnerability\nfrom the CVE link(s) in the References section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux ComputeNode EUS (v. 7.3) - noarch, x86_64\nRed Hat Enterprise Linux ComputeNode Optional EUS (v. 7.3) - x86_64\nRed Hat Enterprise Linux Server EUS (v. 7.3) - noarch, ppc64, ppc64le, s390x, x86_64\nRed Hat Enterprise Linux Server Optional EUS (v. 7.3) - ppc64, ppc64le, x86_64\n\n3. Description:\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system. \n\nSecurity Fix(es):\n\n* A flaw named SegmentSmack was found in the way the Linux kernel handled\nspecially crafted TCP packets. A remote attacker could use this flaw to\ntrigger time and calculation expensive calls to tcp_collapse_ofo_queue()\nand tcp_prune_ofo_queue() functions by sending specially modified packets\nwithin ongoing TCP sessions which could lead to a CPU saturation and hence\na denial of service on the system. Maintaining the denial of service\ncondition requires continuous two-way TCP sessions to a reachable open\nport, thus the attacks cannot be performed using spoofed IP addresses. \n(CVE-2018-5390)\n\n* A flaw named FragmentSmack was found in the way the Linux kernel handled\nreassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use\nthis flaw to trigger time and calculation expensive fragment reassembly\nalgorithm by sending specially crafted packets which could lead to a CPU\nsaturation and hence a denial of service on the system. (CVE-2018-5391)\n\n* kernel: mm: use-after-free in do_get_mempolicy function allows local DoS\nor other unspecified impact (CVE-2018-10675)\n\nFor more details about the security issue(s), including the impact, a CVSS\nscore, and other related information, refer to the CVE page(s) listed in\nthe References section. \n\nRed Hat would like to thank Juha-Matti Tilli (Aalto University - Department\nof Communications and Networking and Nokia Bell Labs) for reporting\nCVE-2018-5390 and CVE-2018-5391. \n\nBug Fix(es):\n\n* On systems running Red Hat Enterprise Linux 7 with Red Hat OpenShift\nContainer Platform 3.5, a node sometimes got into \"NodeNotReady\" state\nafter a CPU softlockup. Consequently, the node was not available. This\nupdate fixes an irq latency source in memory compaction. As a result, nodes\nno longer get into \"NodeNotReady\" state under the described circumstances. \n(BZ#1596281)\n\n* Previously, the kernel source code was missing support to report the\nSpeculative Store Bypass Disable (SSBD) vulnerability status on IBM Power\nSystems and the little-endian variants of IBM Power Systems. As a\nconsequence, the /sys/devices/system/cpu/vulnerabilities/spec_store_bypass\nfile incorrectly reported \"Not affected\" on both CPU architectures. This\nfix updates the kernel source code to properly report the SSBD status\neither as \"Vulnerable\" or \"Mitigation: Kernel entry/exit barrier (TYPE)\"\nwhere TYPE is one of \"eieio\", \"hwsync\", \"fallback\", or \"unknown\". \n(BZ#1612351)\n\n* The hypervisors of Red Hat Enterprise Linux 7 virtual machines (VMs) in\ncertain circumstances mishandled the microcode update in the kernel. As a\nconsequence, the VMs sometimes became unresponsive when booting. This\nupdate applies an upstream patch to avoid early microcode update when\nrunning under a hypervisor. As a result, kernel hangs no longer occur in\nthe described scenario. (BZ#1618388)\n\n4. Solution:\n\nFor details on how to apply this update, which includes the changes\ndescribed in this advisory, refer to:\n\nhttps://access.redhat.com/articles/11258\n\nThe system must be rebooted for this update to take effect. \n\n5. Bugs fixed (https://bugzilla.redhat.com/):\n\n1575065 - CVE-2018-10675 kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact\n1601704 - CVE-2018-5390 kernel: TCP segments with random offsets allow a remote denial of service (SegmentSmack)\n1609664 - CVE-2018-5391 kernel: IP fragments with random offsets allow a remote denial of service (FragmentSmack)\n\n6.

VAR-202310-0175

Vulnerability from variot - Updated: 2025-12-22 22:37

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. The updated image includes new features and bug fixes.

It contains the following bug fixes and changes:

  • Previously, Red Hat OpenShift Container Platform customers using the downloaded manifest bundle with automatic upgrades enabled found that Sensor did not automatically upgrade, and failed with a PRE_FLIGHT_CHECKS_FAILED error. This issue has been fixed. (ROX-19955)

  • RHACS 4.2.2 includes a new default policy called \"Rapid Reset: Denial of Service Vulnerability in HTTP/2 Protocol\". This policy alerts on deployments with images containing components that are susceptible to a Denial of Service (DoS) vulnerability for HTTP/2 servers, based on CVE-2023-44487 and CVE-2023-39325. This policy applies to the build or deploy life cycle stage.

Debian Security Advisory DSA-5522-1 security@debian.org https://www.debian.org/security/ Markus Koschany October 10, 2023 https://www.debian.org/security/faq


Package : tomcat9 CVE ID : CVE-2023-24998 CVE-2023-41080 CVE-2023-42795 CVE-2023-44487 CVE-2023-45648

Several security vulnerabilities have been discovered in the Tomcat servlet and JSP engine.

CVE-2023-24998

Denial of service. Tomcat uses a packaged renamed copy of Apache Commons
FileUpload to provide the file upload functionality defined in the Jakarta
Servlet specification. Apache Tomcat was, therefore, also vulnerable to the
Commons FileUpload vulnerability CVE-2023-24998 as there was no limit to
the number of request parts processed. This resulted in the possibility of
an attacker triggering a DoS with a malicious upload or series of uploads.

CVE-2023-41080

Open redirect. If the ROOT (default) web application is configured to use
FORM authentication then it is possible that a specially crafted URL could
be used to trigger a redirect to an URL of the attackers choice.

CVE-2023-42795

Information Disclosure. When recycling various internal objects, including
the request and the response, prior to re-use by the next request/response,
an error could cause Tomcat to skip some parts of the recycling process
leading to information leaking from the current request/response to the
next.

CVE-2023-44487

DoS caused by HTTP/2 frame overhead (Rapid Reset Attack)

CVE-2023-45648

Request smuggling. Tomcat did not correctly parse HTTP trailer headers. A
specially crafted, invalid trailer header could cause Tomcat to treat a
single request as multiple requests leading to the possibility of request
smuggling when behind a reverse proxy.

For the oldstable distribution (bullseye), these problems have been fixed in version 9.0.43-2~deb11u7.

We recommend that you upgrade your tomcat9 packages.

For the detailed security status of tomcat9 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/tomcat9

Tomcat uses a packaged renamed copy of Apache Commons\n    FileUpload to provide the file upload functionality defined in the Jakarta\n    Servlet specification. Apache Tomcat was, therefore, also vulnerable to the\n    Commons FileUpload vulnerability CVE-2023-24998 as there was no limit to\n    the number of request parts processed. This resulted in the possibility of\n    an attacker triggering a DoS with a malicious upload or series of uploads. \n\nCVE-2023-41080\n\n    Open redirect. If the ROOT (default) web application is configured to use\n    FORM authentication then it is possible that a specially crafted URL could\n    be used to trigger a redirect to an URL of the attackers choice. \n\nCVE-2023-42795\n\n    Information Disclosure. When recycling various internal objects, including\n    the request and the response, prior to re-use by the next request/response,\n    an error could cause Tomcat to skip some parts of the recycling process\n    leading to information leaking from the current request/response to the\n    next. \n\nCVE-2023-44487\n\n    DoS caused by HTTP/2 frame overhead (Rapid Reset Attack)\n\nCVE-2023-45648\n\n    Request smuggling. Tomcat did not correctly parse HTTP trailer headers. A\n    specially crafted, invalid trailer header could cause Tomcat to treat a\n    single request as multiple requests leading to the possibility of request\n    smuggling when behind a reverse proxy. \n\nFor the oldstable distribution (bullseye), these problems have been fixed\nin version 9.0.43-2~deb11u7. \n\nWe recommend that you upgrade your tomcat9 packages. \n\nFor the detailed security status of tomcat9 please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/tomcat9\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\ne3g3nA1rbB1jlx6cvPqWBFItXW8800mJ0CXHb8EN8jKdB5BnooY=\n=6KYM\n-----END PGP SIGNATURE-----\n. \n\n\n\n\nDescription:\n\nVarnish Cache is a high-performance HTTP accelerator.

VAR-201702-0814

Vulnerability from variot - Updated: 2025-04-20 23:34

A vulnerability in the received packet parser of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) software could allow an unauthenticated, remote attacker to cause a reload of the affected system, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient size validation of user-supplied data. An attacker could exploit this vulnerability by sending crafted H.224 data in Real-Time Transport Protocol (RTP) packets in an H.323 call. An exploit could allow the attacker to overflow a buffer in a cache that belongs to the received packet parser, which will result in a crash of the application, resulting in a DoS condition. All versions of Cisco Expressway Series Software and Cisco TelePresence VCS Software prior to version X8.8.2 are vulnerable. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Cisco Bug IDs: CSCus99263

    "data": "A vulnerability in the received packet parser of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) software could allow an unauthenticated, remote attacker to cause a reload of the affected system, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient size validation of user-supplied data. An attacker could exploit this vulnerability by sending crafted H.224 data in Real-Time Transport Protocol (RTP) packets in an H.323 call. An exploit could allow the attacker to overflow a buffer in a cache that belongs to the received packet parser, which will result in a crash of the application, resulting in a DoS condition. All versions of Cisco Expressway Series Software and Cisco TelePresence VCS Software prior to version X8.8.2 are vulnerable. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Cisco Bug IDs: CSCus99263",

VAR-201503-0157

Vulnerability from variot - Updated: 2025-04-13 23:26

The Session Description Protocol (SDP) implementation in Cisco TelePresence Video Communication Server (VCS) and Cisco Expressway before X8.2 and Cisco TelePresence Conductor before XC2.4 allows remote attackers to cause a denial of service (mishandled exception and device reload) via a crafted media description, aka Bug IDs CSCus96593 and CSCun73192. Multiple Cisco products are prone to a remote denial-of-service vulnerability. An attacker can exploit this issue to reload an affected device, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCus96593 and CSCun73192

Vulnerability from variot - Updated: 2024-11-23 22:44

A vulnerability in the Traversal Using Relays around NAT (TURN) server component of Cisco Expressway software could allow an unauthenticated, remote attacker to bypass security controls and send network traffic to restricted destinations. The vulnerability is due to improper validation of specific connection information by the TURN server within the affected software. An attacker could exploit this issue by sending specially crafted network traffic to the affected software. A successful exploit could allow the attacker to send traffic through the affected software to destinations beyond the application, possibly allowing the attacker to gain unauthorized network access. Cisco Expressway The software contains a vulnerability in privilege management.Information may be obtained and information may be tampered with. The software provides simple, highly secure access for users outside the firewall, helping remote workers work more efficiently on the device of their choice

    "data": "A vulnerability in the Traversal Using Relays around NAT (TURN) server component of Cisco Expressway software could allow an unauthenticated, remote attacker to bypass security controls and send network traffic to restricted destinations. The vulnerability is due to improper validation of specific connection information by the TURN server within the affected software. An attacker could exploit this issue by sending specially crafted network traffic to the affected software. A successful exploit could allow the attacker to send traffic through the affected software to destinations beyond the application, possibly allowing the attacker to gain unauthorized network access. Cisco Expressway The software contains a vulnerability in privilege management.Information may be obtained and information may be tampered with. The software provides simple, highly secure access for users outside the firewall, helping remote workers work more efficiently on the device of their choice",

VAR-202010-1053

Vulnerability from variot - Updated: 2024-11-23 22:37

A vulnerability in the Session Initiation Protocol (SIP) of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect handling of incoming SIP traffic. An attacker could exploit this vulnerability by sending a series of SIP packets to an affected device. A successful exploit could allow the attacker to exhaust memory on an affected device, causing it to crash and leading to a DoS condition. Cisco Expressway Series is an advanced collaboration gateway for unified communications

VAR-201904-0248

Vulnerability from variot - Updated: 2024-11-23 21:52

A vulnerability in the FindMe feature of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user of the interface to follow a maliciously crafted link. A successful exploit could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. The arbitrary actions include adding an attacker-controlled device and redirecting calls intended for a specific user. For more information about CSRF attacks and potential mitigations, see Understanding Cross-Site Request Forgery Threat Vectors. This vulnerability is fixed in software version X12.5.1 and later. Other attacks are also possible. This issue is being tracked by Cisco Bug ID CSCvn47520

    "data": "A vulnerability in the FindMe feature of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user of the interface to follow a maliciously crafted link. A successful exploit could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. The arbitrary actions include adding an attacker-controlled device and redirecting calls intended for a specific user. For more information about CSRF attacks and potential mitigations, see Understanding Cross-Site Request Forgery Threat Vectors. This vulnerability is fixed in software version X12.5.1 and later. Other attacks are also possible. \nThis issue is being tracked by Cisco Bug ID CSCvn47520",

VAR-202207-0215

Vulnerability from variot - Updated: 2024-08-14 14:43

Multiple vulnerabilities in the API and in the web-based management interface of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow a remote attacker to overwrite arbitrary files or conduct null byte poisoning attacks on an affected device. Note: Cisco Expressway Series refers to the Expressway Control (Expressway-C) device and the Expressway Edge (Expressway-E) device. For more information about these vulnerabilities, see the Details section of this advisory. The software provides simple, highly secure access for users outside the firewall, helping remote workers work more efficiently on the device of their choice

Title
Cisco Expressway Series and TelePresence Video Communication Server Image Verification Vulnerability
Summary
A vulnerability in the image verification function of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to execute code with internal user privileges on the underlying operating system. The vulnerability is due to insufficient validation of the content of upgrade packages. An attacker could exploit this vulnerability by uploading a malicious archive to the Upgrade page of the administrative web interface. A successful exploit could allow the attacker to execute code with user-level privileges (the _nobody account) on the underlying operating system.
