A vulnerability, which was classified as problematic, was found in Jenkins up to 2.153/LTS 2.138.3 (Continuous Integration Software). Affected is an unknown code block of the file User.java of the component Logging. The manipulation as part of a User Name leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on availability. CVE summarizes:
