Technical details
An Insecure Direct Object Reference (IDOR) vulnerability exists in the 'PUT /api/v1/accounts/{pk}/password/' endpoint of Modoboa. The application fails to properly validate that the authenticated domain administrator has the authority to modify the specific user account identified by the primary key ({pk}) in the request. By manipulating this identifier, an attacker with low-level domain administrative privileges can reset the password of any user, including super-administrators, bypassing object-level access controls. This vulnerability is addressed in version 2.9.0.
