Technical details
An OS command injection vulnerability exists in Tuleap Enterprise Edition versions 17.0 through 17.5, allowing arbitrary command execution on the server. The advisory does not specify the vulnerable component, attack vector details, or required preconditions; however, command injection typically requires the ability to provide input to a function that invokes system commands without proper sanitization. Exploitation grants an attacker the ability to run arbitrary code with the privileges of the Tuleap application process.
