Details

Jenkins Credentials Binding Plugin 719.v80e905ef14eb_ and earlier does not sanitize file names for file and zip file credentials, allowing attackers able to provide credentials to a job to write files to arbitrary locations on the node filesystem, which can lead to remote code execution if Jenkins is configured to allow a low-privileged user to configure file or zip file credentials used for a job running on the built-in node.
