CVE-2022-34177: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

June 24, 2022 (updated July 5, 2022)

Jenkins Pipeline: Input Step Plugin 448.v37cea_9a_10a_70 and earlier archives files uploaded for file parameters for Pipeline input steps on the controller as part of build metadata, using the parameter name without sanitization as a relative path inside a build-related directory, allowing attackers able to configure Pipelines to create or replace arbitrary files on the Jenkins controller file system with attacker-specified content.
