Microsoft Exchange Server Elevation of Privilege Vulnerability

A critical flaw in Microsoft Exchange Server allows an authenticated user to gain system administrator privileges without proper authorization. This vulnerability enables attackers who have basic access to take complete control of the email server.

An authentication bypass vulnerability (CWE-287) in Microsoft Exchange Server permits privilege escalation from authenticated user to SYSTEM level. The attack requires valid user credentials but no additional exploitation; successful exploitation grants complete administrative control over the Exchange environment.
