CISA KEV Advisory
Jenkins Command Line Interface (CLI) Path Traversal Vulnerability
Jenkins Command Line Interface (CLI) contains a path traversal vulnerability that allows attackers limited read access to certain files, which can lead to code execution.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
This path traversal vulnerability in the Jenkins Command Line Interface (CLI) allows attackers to read certain files, which can then lead to remote code execution. This could allow an attacker to gain control over the Jenkins instance. The very high EPSS score indicates a high likelihood of exploitation, making this a critical vulnerability.
This vulnerability is actively being exploited in the wild and is listed in CISA's KEV catalog, confirming its active exploitation. The CLI nature suggests it could be remotely exploitable if the CLI is exposed.
Update Jenkins to the latest version to address the path traversal vulnerability. Restrict access to the Jenkins CLI and ensure proper authentication is in place.
Technical Analysis
CVE-2024-23897 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2024-23897 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
