CVE-2020-3155 (GCVE-0-2020-3155)

Vulnerability from cvelistv5 – Published: 2020-03-04 18:40 – Updated: 2024-11-15 17:35
VLAI
Title
Cisco Intelligent Proximity SSL Certificate Validation Vulnerability
Summary
A vulnerability in the SSL implementation of the Cisco Intelligent Proximity solution could allow an unauthenticated, remote attacker to view or alter information shared on Cisco Webex video devices and Cisco collaboration endpoints if the products meet the conditions described in the Vulnerable Products section. The vulnerability is due to a lack of validation of the SSL server certificate received when establishing a connection to a Cisco Webex video device or a Cisco collaboration endpoint. An attacker could exploit this vulnerability by using man in the middle (MITM) techniques to intercept the traffic between the affected client and an endpoint, and then using a forged certificate to impersonate the endpoint. Depending on the configuration of the endpoint, an exploit could allow the attacker to view presentation content shared on it, modify any content being presented by the victim, or have access to call controls. This vulnerability does not affect cloud registered collaboration endpoints.

Title
Cisco Webex Meetings Desktop App for Mac Update Feature Code Execution Vulnerability
Summary
A vulnerability in the software update feature of Cisco Webex Meetings Desktop App for Mac could allow an unauthenticated, remote attacker to execute arbitrary code on an affected system. The vulnerability is due to improper validation of cryptographic protections on files that are downloaded by the application as part of a software update. An attacker could exploit this vulnerability by persuading a user to go to a website that returns files to the client that are similar to files that are returned from a valid Webex website. The client may fail to properly validate the cryptographic protections of the provided files before executing them as part of an update. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the user.

CVE-2020-3557 (GCVE-0-2020-3557)

Vulnerability from cvelistv5 – Published: 2020-10-21 18:41 – Updated: 2024-11-13 17:45
VLAI
Title
Cisco Firepower Management Center Software Denial of Service Vulnerability
Summary
A vulnerability in the host input API daemon of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper certificate validation. An attacker could exploit this vulnerability by sending a crafted data stream to the host input daemon of the affected device. A successful exploit could allow the attacker to cause the host input daemon to restart. The attacker could use repeated attacks to cause the daemon to continuously reload, creating a DoS condition for the API.

Title
Kubernetes Operator generates potentially insecure certificates
Summary
X.509 certificates generated by the MongoDB Enterprise Kubernetes Operator may allow an attacker with access to the Kubernetes cluster improper access to MongoDB instances. Customers who do not use X.509 authentication, and those who do not use the Operator to generate their X.509 certificates are unaffected. This issue affects MongoDB Enterprise Kubernetes Operator version 1.0, MongoDB Enterprise Kubernetes Operator version 1.1, MongoDB Enterprise Kubernetes Operator version 1.2 versions prior to 1.2.4, MongoDB Enterprise Kubernetes Operator version 1.3 versions prior to 1.3.1, 1.2, 1.4 versions prior to 1.4.4.

Mitigation

Phases: Architecture and Design, Implementation

Description:

  • Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation

Phase: Implementation

Description:

  • If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CAPEC-459: Creating a Rogue Certification Authority Certificate

An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.

CAPEC-475: Signature Spoofing by Improper Validation

An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
