Technical details
The vulnerability is an improper privilege management issue in AuthProfile self-update functionality. Non-admin users can modify their own authentication profile to enable WA surrogate authentication (account impersonation), a privilege that should be restricted to administrators. An authenticated attacker with a regular user account can exploit this by modifying their profile directly, gaining the ability to impersonate other users without requiring admin rights.

- Apache Syncope 3.0.12 through 3.0.16, 4.0.0-M0 through 4.0.8, 4.1.0-M0 through 4.1.3
