Microsoft Exchange Server fails to properly decode MIME email messages

Overview

Microsoft Exchange Server contains a remote code execution vulnerability that could enable an attacker to execute arbitrary code and gain complete control of the vulnerable system.

When an email message containing base64 encoded content is opened, Microsoft Exchange Server does not properly decode the base64 content. An attacker could send a specially crafted email that, when opened, could allow the attacker to execute arbitrary code. The attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
