Microsoft Message Queuing Service Stack Buffer Overflow Vulnerability

Risk

High

Date Discovered

December 11, 2007

Description

Microsoft Message Queuing (MSMQ) is prone to a stack-based buffer-overflow vulnerability because the software fails to perform adequate boundary checks on user-supplied data. An attacker can exploit this issue to execute arbitrary code with SYSTEM-level privileges, facilitating the complete compromise of affected computers. Failed exploit attempts will result in a denial-of-service condition. This issue is exploitable remotely on all Windows 2000 systems and locally on Windows XP, provided that the affected component is installed.

Recommendations

Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.

Given the local nature of this issue (for Windows XP and Windows 2000 Professional targets), grant only trusted and accountable individuals access to affected computers.

Block external access at the network boundary, unless external parties require service.

If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from a successful exploit.

Implement multiple redundant layers of security.

Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.

Disable any services that are not needed.

Disable the MSMQ component if it is present and not needed on the computer.
