Microsoft Windows Internet Name Service (WINS) Failed Response Remote Code Execution Vulnerability

Risk

High

Date Discovered

May 10, 2011

Description

Microsoft Windows Internet Name Service (WINS) is prone to a remote code-execution vulnerability because it fails to properly validate certain replication packets. An attacker can exploit this issue to execute arbitrary code with elevated privileges. Successful attacks will result in a complete compromise of affected computers. Failed exploit attempts will result in a denial-of-service condition.

Recommendations

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

If possible, block external access to the affected application. Permit access for trusted or internal networks and hosts only.

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.

Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
The vendor has released an advisory and updates to address this issue. Please see the references for more information.
