A path traversal vulnerability in Jenkins 2.185 and earlier, LTS 2.176.1 and earlier in core/src/main/java/hudson/model/FileParameterValue.java allowed attackers with Job/Configure permission to define a file parameter with a file name outside the intended directory, resulting in an arbitrary file write on the Jenkins master when scheduling a build.
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.
