Description

A remote overflow exists in Mercur Messaging/Mailserver. The IMAP service fails to provide proper boundary checking when processing NTLM data resulting in a stack-based overflow. With a specially crafted NTLM authentication request provided with a long NTLMSSP argument, an attacker can cause arbitrary code execution resulting in a loss of integrity.

Classification

Location: Remote / Network Access
Attack Type: Input Manipulation
Impact: Loss of Integrity
Exploit: Exploit Public
Disclosure: OSVDB Verified

Technical

The Mercur IMAP service runs by default as LOCAL SYSTEM, so an attacker could potentially gain complete control over the affected system.

Solution

Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
