The management frontend does not require the old password for changing the password to a new one. An authenticated attacker may perform password setting attacks via XSRF without knowing the current password. An attacker that stole a Session ID (cookie) is able to gain persistent access by changing the password.

Fix proposal:

A password change should require the old password to be provided.

Vendor fix:

When a user is changing their password, they are now required to enter their current password.
