It is critical to update to the latest Jenkins versions due to a recently disclosed vulnerability (CVE-2024-23897). The security flaw in Jenkins versions before 2.442 and LTS 2.426.3 allows attackers to read sensitive information and execute arbitrary code. Organizations are urged to update to the patched versions or disable the command line interface as a temporary workaround.
Key takeaways from the meeting notes:
– There is a critical vulnerability (CVE-2024-23897) affecting Jenkins versions before 2.442 and LTS 2.426.3. The vulnerability allows attackers to read arbitrary files on the Jenkins controller file system and could lead to unauthorized actions such as executing arbitrary code remotely and decrypting secrets.
– Sonar, a code quality platform, identified the issue, and a proof-of-concept (PoC) exploit code targeting the critical vulnerability has been publicly available on GitHub.
– It is imperative for organizations to update to Jenkins versions 2.442 or LTS 2.426.3, which resolve the bug by disabling the problematic feature in the command parser. As a temporary workaround, administrators can disable access to the built-in command line interface (CLI) of Jenkins to prevent exploitation.
– Jenkins, being a widely used tool for continuous integration and continuous delivery (CI/CD) with a significant market share, is a highly attractive target for threat actors.
