CVE-2021-21690 [CRITICAL] 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-2486 / CVE-2021-21690: Agent processes are able to completely bypass file path filtering by wrapping the file operation in an agent file path.
We expect that most of these vulnerabilities have been present since [SECURITY-144 was addressed in the 2014-10-30 security advisory

jenkins: Agent processes are able to completely bypass file path filtering by wrapping the file operation in an agent file path
Agent processes are able to completely bypass file path filtering by wrapping the file operation in an agent file path in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
A file path filtering bypass vulnerability was found in Jenkins. Agent processes are able to completely bypass file path filtering by wrapping the file operation in an agent file path. This may allow an attacker who controls the agent process to get read and write access to arbitrary files on the Jenkins controller file system.
Mitigation: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the af
