Description
The vulnerability allows a remote user to execute arbitrary shell commands.
The vulnerability exists due to improper neutralization of special elements used in an os command in the system.run shell wrapper when invoking bash -lc with request-scoped environment variables. A remote privileged user can supply crafted SHELLOPTS and PS4 environment values to execute arbitrary shell commands.
Exploitation requires the ability to invoke system.run with request-scoped env values, and the issue affects allowlist mode for shell wrappers.
