Summary

The flaw lies in the system.execute() function exposed to the scripting engine of openEQUELLA, prior to version 2026.1, which runs supplied operating system commands without validation or an allow-list of permitted executables. An attacker who holds a low-privilege account able to create or edit scripts, with no user interaction required, can run arbitrary commands over the network with the privileges of the openEQUELLA service account.
