Summary

Jenkins Script Security Plugin 1402.v94c9ce464861 and earlier does not reject Groovy AST transformation annotations carrying an extensions member, allowing attackers able to run sandboxed Groovy scripts to execute code outside the sandbox if a suitable script is present on the classpath of the component that evaluates the script.

This flaw has an Important impact as the Jenkins Script Security Plugin shipped in Red Hat OpenShift Container Platform is susceptible to a sandbox bypass. Exploitation requires a suitable script to be present on the classpath, increasing attack complexity.

Red Hat severity: Important — CVSS 8.5 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H). Weakness: CWE-917.
