Summary:
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.
