The host is installed with Jenkins LTS through 2.138.1 or Jenkins rolling release through 2.145 and is prone to a path traversal vulnerability. A flaw is present in the application, which fails to properly handle an issue in core/src/main/java/hudson/model/FileParameterValue.java. Successful exploitation could allow 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.
