CVE-2020-2279 [CRITICAL] Sandbox bypass vulnerability in Jenkins Script Security Plugin
Sandbox bypass vulnerability in Jenkins Script Security Plugin
Jenkins Script Security Plugin provides a sandbox feature that allows low privileged users to define scripts, including Pipelines, that are generally safe to execute. Calls to code defined inside a sandboxed script are intercepted, and various allowlists are checked to determine whether the call is to be allowed.
In Script Security Plugin 1.75 and 1.66.5, any calls from outside a sandboxed script to code defined inside a sandboxed script were always allowed. As sandboxed scripts can communicate their results through script return values and similar mechanisms, this could result in code defined inside of a sandboxed script to be called without sandbox protection.
This vulnerability allows attackers with permission to define a
