A tampering vulnerability exists when Microsoft Exchange Server fails to properly handle profile data. An attacker who successfully exploited this vulnerability could modify a targeted user’s profile data.

To exploit the vulnerability, an attacker would need to be authenticated on an affected Exchange Server. The attacker would then need to send a specially modified request to the server, targeting a specific user.

The security update addresses the vulnerability by modifying how Microsoft Exchange Server handles profile data.
