CVE-2021-21685 [CRITICAL] CWE-862 Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins
Multiple vulnerabilities allow bypassing path filtering of agent-to-controller access control in Jenkins
The agent-to-controller security subsystem limits which files on the Jenkins controller can be accessed by agent processes.
Multiple vulnerabilities in the file path filtering implementation of Jenkins 2.318 and earlier, LTS 2.303.2 and earlier allow agent processes to read and write arbitrary files on the Jenkins controller file system, and obtain some information about Jenkins controller file systems.
SECURITY-2427 / CVE-2021-21685: `FilePath#mkdirs` does not check permission to create parent directories.
We expect that most of these vulnerabilities have been present since [SECURITY-144 was addressed in the 2014-10-30 security advisory](https://www.jenkins.io/security/advisory/201
