CVE-2024-23897
Jenkins Command Line Interface (CLI) Path Traversal Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 9 September 2024). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
Description
Jenkins 2.441 and earlier, LTS 2.426.2 and earlier does not disable a feature of its CLI command parser that replaces an '@' character followed by a file path in an argument with the file's contents, allowing unauthenticated attackers to read arbitrary files on the Jenkins controller file system.
