User Enumeration in MCO

Description

MCO is vulnerable to User Enumeration through authentication-related functionalities.

An attacker can leverage these differences to enumerate valid usernames and email addresses. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
