CVE-2019-1003051: Jenkins IRC Plugin stores credentials unencrypted in its global configuration file on the Jenkins master wh...

Security readout for executives and security teams

Jenkins IRC Plugin stored credentials in plaintext in a global configuration file on the Jenkins master. Anyone with access to that master file system could view those secrets. The main business risk is credential exposure from an already-sensitive server, not direct remote code execution based on the provided sources. Organizations using Jenkins with the IRC Plugin installed as of the 2019 advisory date are potentially exposed, especially where multiple administrators, build users, or automation accounts can access the Jenkins master file system. Treat this as a credential exposure issue on a high-value automation server. Prioritize environments where Jenkins master file-system access is broadly granted or where the affected credentials could unlock other business systems. Mitigation focus: Check Jenkins advisory SECURITY-829 and current plugin guidance.; Restrict Jenkins master file-system access to trusted administrators only.; Remove the IRC Plugin if it is no longer required..
