Microsoft Windows Workstation Service NetpManageIPCConnect Remote Code Execution Vulnerability

Risk

High

Date Discovered

November 14, 2006

Description

Microsoft Windows Workstation service is prone to a remote code-execution vulnerability. Exploiting this issue allows remote, anonymous attackers to execute arbitrary machine code on affected computers with SYSTEM-level privileges. This facilitates the complete compromise of affected computers. Attackers require administrative privileges to exploit this issue on Windows XP SP2 computers. Anonymous attackers may exploit this issue on Windows 2000 computers.

Recommendations

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

To limit the potential for remote attackers to exploit this issue, allow only trusted hosts and networks to connect to computers running the affected software.

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 successful exploits.

Implement multiple redundant layers of security.

As an added precaution, deploy memory-protection schemes (such as nonexecutable stack/heap configuration and randomly mapped memory segments). This may complicate exploits of memory-corruption vulnerabilities.
Microsoft has released an advisory along with fixes to address this issue. Please see the referenced advisory for more information.
