Jenkins Sidebar Link Plugin vulnerable to Path Traversal

Source: GitHub Advisory Database (reviewed) Moderate CVE-2023-32985

Packages

EcosystemPackageAffectedFixed in
Maven org.jenkins-ci.plugins:sidebar-link < 2.2.2 2.2.2

Details

As written in the advisory (Markdown source, shown as plain text).

Jenkins Sidebar Link Plugin allows specifying files in the `userContent/` directory for use as link icons. Sidebar Link Plugin 2.2.1 and earlier does not restrict the path of files in a method implementing form validation. This allows attackers with Overall/Read permission to check for the existence of an attacker-specified file path on the Jenkins controller file system. Sidebar Link Plugin 2.2.2 ensures that only files located within the expected `userContent/` directory can be accessed.
