Title
Cleartext transmission of sensitive materials in aws/sagemaker-python-sdk
Summary
The Amazon SageMaker Python SDK before v3.2.0 and v2.256.0 includes the ModelBuilder HMAC signing key in the cleartext response elements of the DescribeTrainingJob function. A third party with permissions to both call this API and permissions to modify objects in the Training Jobs S3 output location may have the ability to upload arbitrary artifacts which are executed the next time the Training Job is invoked.

Summary
A physical attack vulnerability exists in certain Moxa industrial computers using TPM-backed LUKS full-disk encryption on Moxa Industrial Linux 3, where the discrete TPM is connected to the CPU via an SPI bus. Exploitation requires invasive physical access, including opening the device and attaching external equipment to the SPI bus to capture TPM communications. If successful, the captured data may allow offline decryption of eMMC contents. This attack cannot be performed through brief or opportunistic physical access and requires extended physical access, possession of the device, appropriate equipment, and sufficient time for signal capture and analysis. Remote exploitation is not possible.

Title
[0day-rubbish] Lightstreamer Server 7.4.8 Shipped placeholder JMX/RMI credentials plus MLet remote class loading to root RCE (9.8)
Summary
0day Rubbish Research Team is publicly disclosing a vulnerability in
Lightstreamer Server 7.4.8 build 3506 ENTERPRISE (with JMS Extender 2.1.0).
Type: a hard-coded placeholder credential shipped in the distribution
(user_changeme / password_changeme) authenticating a cleartext RMI management
connector on TCP 8888 bound to every interface; because the connector exposes
createMBean, an attacker registers javax.management.loading.MLet and calls
getMBeansFromURL against an origin they control, and the loaded MBean's
constructor runs Runtime.exec (CWE-798, CWE-319)
Scoring. This finding is dual-scored because remote reach depends on the
shipped placeholder being left unchanged. Both figures are published:
- PRIMARY, 9.8 Critical, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. This
applies with the shipped placeholder credential unchanged, which is how the
distribution archive delivers it (byte-identical to the deployed file, with no
documented first-login rotation gate).
- CONDITIONAL, 7.2 High, CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. This
applies where an operator has rotated the credential but createMBean and MLet
remain exposed: the step then needs a genuinely privileged account.
Impact: arbitrary command execution as the broker process user, which was root
in the tested deployment. Configuration, TLS material and keystores, streamed
application data and any other credential configured in lightstreamer_conf.xml
are all reachable; the payload MBean stays registered for the JVM lifetime as a
persistent command channel.
Authentication: none beyond the shipped placeholder pair (empty and wrong
credentials were both rejected with SecurityException, so the defect is the
credential's provenance, not a bypassable check).
Verification boundary, stated plainly. We verified the chain end to end over
loopback against a broker unpacked from the distribution archive and started as
root, with the attacker HTTP origin simulated on the same research host: four
runs (three against the jmxrmi platform MBean server, one against the lsjmx
application MBean server), an out-of-band HTTP access log proving a uniquely
named JAR was really fetched rather than cached, runCmd returning uid=0(root)
and a root-owned proof file. Remote cross-network reach is an assessment of the
shipped bind topology (TCP 8888 binds 0.0.0.0 because <listening_interface> is
commented out, with no host firewall rule dropping it), not an observed attack
crossing a network boundary. The one genuine precondition is that the operator
has not replaced the shipped placeholder pair.
This is a distinct defect from the separate unauthenticated jvmtiAgentLoad
primitive we are disclosing in the same product; it reaches code execution via
remote Java class loading rather than a native agent load.

Title
HP Easy Start for macOS: CVE-2026-12554 / CVE-2026-12555 / CVE-2026-12556
Summary
Hello Full Disclosure list,
Cipher Security Labs has published technical details for three
High-severity vulnerabilities affecting HP Easy Start for macOS. The
issues were coordinated with HP and are addressed in HP Easy Start
2.16.7.260722 and later under HPSBPI04124.
Research title:
Rooted in Trust: Breaking HP Easy Start’s macOS Privilege Boundaries
Affected product:
HP Easy Start for macOS
Affected versions:
Versions prior to 2.16.7.260722
Validated vulnerable sample:
2.16.0 (build 251010)
Fixed:
2.16.7.260722 and later
CVE-2026-12554
CVSS 4.0: 8.5 High
CWE-1104: Use of Unmaintained Third-Party Components
The affected software-download path contained an OSPFTP stack wired
into component acquisition, including fallback URL-scheme handling.
The research does not claim that every installation uses FTP on the
normal path; the finding is that an unmaintained FTP-capable component
remained active on the privileged software-delivery surface.
CVE-2026-12555
CVSS 4.0: 7.7 High
CWE-379: Creation of Temporary File in Directory with Insecure Permissions
The HP Uninstaller used predictable paths under /tmp and /private/tmp
while operating with administrative privileges. An unprivileged local
user could prepare a symbolic link before the elevated process opened
the path. In our PoC, after the user approved the normal macOS
administrative prompt, HP-generated log data was appended through the
symlink to an attacker-selected proof file as root.
We intentionally describe this as privileged file
modification/corruption rather than unrestricted arbitrary file write:
destination control is demonstrated, but the log content itself is
generated by HP Easy Start. Follow-on privilege escalation would
require a suitable environment-specific target and is not automatic.
CVE-2026-12556
CVSS 4.0: 7.7 High
CWE-319: Cleartext Transmission of Sensitive Information
HP Easy Start 2.16.0 set NSAllowsArbitraryLoads=true in its App
Transport Security policy and retained cleartext FTP as a
software-download fallback. Together these conditions expanded the
circumstances in which a network-positioned attacker could interfere
with software-component acquisition when the primary scheme failed.
The research does not claim that NSAllowsArbitraryLoads alone disables
certificate validation, that every install falls back to FTP, or that
package substitution automatically yields code execution. Those are
separate conditions and are treated separately in the analysis.
Related design note — not a fourth CVE
The 2.16.0 build also contained SWHelper, a privileged helper using
Apple’s deprecated AuthorizationExecuteWithPrivileges API. The legacy
API and path-oriented privileged install flow were confirmed, but an
end-to-end package-swap TOCTOU against the production staging path was
not demonstrated. This is therefore documented only as a risky
privilege-boundary design with conditional exploitability.
Remediation validation
In 2.16.7 (build 260722), Cipher Security Labs validated that:
• the vulnerable Uninstaller bundle was removed from the package tested;
• OSPFTP download classes and FTP software-download markers were absent;
• blanket ATS relaxation was tightened;
• SWHelper and AuthorizationExecuteWithPrivileges were removed;
• a new privileged helper used SMAppService and NSXPCConnection;
• the helper restricted clients by code-signing identity; and
• package SHA-256 was verified using an already-open file descriptor
before invoking /usr/sbin/installer.

This is therefore documented only as a risky\nprivilege-boundary design with conditional exploitability.\n\nRemediation validation\n\nIn 2.16.7 (build 260722), Cipher Security Labs validated that:\n\n\u2022 the vulnerable Uninstaller bundle was removed from the package tested;\n\u2022 OSPFTP download classes and FTP software-download markers were absent;\n\u2022 blanket ATS relaxation was tightened;\n\u2022 SWHelper and AuthorizationExecuteWithPrivileges were removed;\n\u2022 a new privileged helper used SMAppService and NSXPCConnection;\n\u2022 the helper restricted clients by code-signing identity; and\n\u2022 package SHA-256 was verified using an already-open file descriptor\nbefore invoking /usr/sbin/installer.\n\nResearch:\nhttps://ciphersecuritylabs.com/papers/rooted-in-trust-breaking-hp-easy-starts-macos-privilege-boundaries\n\nHP advisory:\nhttps://support.hp.com/us-en/document/ish_15512340-15512362-16/hpsbpi04124\n\nCVE records:\nhttps://www.cve.org/CVERecord?id=CVE-2026-12554\nhttps://www.cve.org/CVERecord?id=CVE-2026-12555\nhttps://www.cve.org/CVERecord?id=CVE-2026-12556\n\nResearcher:\nNir Yehoshua\nCipher Security Labs\nnir () ciphersecuritylabs com\nhttps://ciphersecuritylabs.com\n\nRegards,\nNir\n_______________________________________________\nSent through the Full Disclosure mailing list\nhttps://nmap.org/mailman/listinfo/fulldisclosure\nWeb Archives \u0026 RSS: https://seclists.org/fulldisclosure/"

Mitigation
Architecture and Design
Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
Mitigation
Implementation
When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
Mitigation
Implementation
When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
Mitigation
Testing
Use tools and techniques that require manual (human) analysis, such as penetration testing, threat modeling, and interactive tools that allow the tester to record and modify an active session. These may be more effective than strictly automated techniques. This is especially the case with weaknesses that are related to design and business rules.
Mitigation
Operation
Configure servers to use encrypted channels for communication, which may include SSL or other secure protocols.
CAPEC-102: Session Sidejacking
Session sidejacking takes advantage of an unencrypted communication channel between a victim and target system. The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.
CAPEC-117: Interception
An adversary monitors data streams to or from the target for information gathering purposes. This attack may be undertaken to solely gather sensitive information or to support a further attack against the target. This attack pattern can involve sniffing network traffic as well as other types of data streams (e.g. radio). The adversary can attempt to initiate the establishment of a data stream or passively observe the communications as they unfold. In all variants of this attack, the adversary is not the intended recipient of the data stream. In contrast to other means of gathering information (e.g., targeting data leaks), the adversary must actively position themself so as to observe explicit data channels (e.g. network traffic) and read the content. However, this attack differs from a Adversary-In-the-Middle (CAPEC-94) attack, as the adversary does not alter the content of the communications nor forward data to the intended recipient.
CAPEC-383: Harvesting Information via API Event Monitoring
An adversary hosts an event within an application framework and then monitors the data exchanged during the course of the event for the purpose of harvesting any important data leaked during the transactions. One example could be harvesting lists of usernames or userIDs for the purpose of sending spam messages to those users. One example of this type of attack involves the adversary creating an event within the sub-application. Assume the adversary hosts a "virtual sale" of rare items. As other users enter the event, the attacker records via AiTM (CAPEC-94) proxy the user_ids and usernames of everyone who attends. The adversary would then be able to spam those users within the application using an automated script.
CAPEC-477: Signature Spoofing by Mixing Signed and Unsigned Content
An attacker exploits the underlying complexity of a data structure that allows for both signed and unsigned content, to cause unsigned data to be processed as though it were signed data.
CAPEC-65: Sniff Application Code
An adversary passively sniffs network communications and captures application code bound for an authorized client. Once obtained, they can use it as-is, or through reverse-engineering glean sensitive information or exploit the trust relationship between the client and server. Such code may belong to a dynamic update to the client, a patch being applied to a client component or any such interaction where the client is authorized to communicate with the server.
