Summary

CVE-2024-23897 is a critical-severity Path Traversal (CWE-22) vulnerability in Jenkins Jenkins. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Jenkins 2.441 and earlier, along with LTS 2.426.2 and earlier, contains a vulnerability in its CLI command parser. The parser fails to disable a feature that substitutes an argument beginning with '@' followed by a file path with the contents of that file on the Jenkins controller file system. This path traversal issue is tracked as CWE-22 and CWE-27 and carries a CVSS 3.1 score of 9.8.

Unauthenticated attackers can supply crafted CLI arguments over the network to read arbitrary files on the controller. Successful exploitation grants access to sensitive configuration data, credentials, and other file contents, enabling further compromise of confidentiality, integrity, and availability without any user interaction or authentication.

The Jenkins security advisory for SECURITY-3314 and related references describe the affected component and direct administrators to upgrade to patched releases. Public exploit code and scanning tools have been published, and the CVE maintains a high EPSS score with a peak of 0.9735, indicating sustained exploitation interest after disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

Secure SDLC practices directly require input validation and path sanitization that prevent directory traversal flaws.

ID.RA-01 partial match

Vulnerability identification processes will discover path traversal weaknesses during code or configuration review.

PR.AA-05 partial match
prevents

Least-privilege file permissions and access enforcement can limit the damage from a successful traversal.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

prevents

Secure coding standards require neutralizing '../' sequences and using safe file APIs, eliminating this exact weakness.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

mitigates

Information access restriction limits which files an application may read or write.
