Naveen Sunkavally, chief architect at Horizon3.ai, has just published “CVE-2024-23897: Assessing the Impact of the Jenkins Arbitrary File Leak Vulnerability,” an analysis of the vulnerability for which Jenkins issued a security advisory on January 24, 2024 re CVE-2024-23897, affecting the Jenkins continuous integration/continuous development (CI/CD) software development tool.
Naveen notes that the advisory set off alarm bells among the infosec community because the potential impact is huge: Jenkins is widely deployed, with tens of thousands of public-facing installs, and the Jenkins advisory was clear that this vulnerability could lead to remote code execution. Jenkins is a common target for attackers, and, as of this writing, there are four prior Jenkins-related vulnerabilities in CISA’s catalog of Known Exploited Vulnerabilities.
His analysis and advice, issued today for users of Jenkins is: “Don’t panic… unless you need to. This is a textbook example of a vulnerability whose true impact can only be accurately assessed within the context of your environment. The typical Jenkins install will not be exploitable by unauthenticated attackers. However, there are a few factors that could significantly increase the potential for damage, elevating this to a truly critical vulnerability.”
His post discusses those factors and how to gain an accurate assessment of risk.
