Risk
High
Date Discovered

Description
Microsoft Windows is prone to a remote code-execution vulnerability that affects the Print Spooler Service.
A remote attacker can exploit this issue to execute code with SYSTEM-level privileges. Local attackers able to submit print jobs can exploit this issue to gain elevated privileges.
NOTE: To exploit this issue, an attacker must have permissions to submit print jobs on the vulnerable system. Guest access to shared print services is enabled by default on Windows XP; later systems will require the attacker to authenticate to the server, or require the server to be configured to allow anonymous access.
Recommendations
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 exploitation.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 explained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Updates are available; please see the references for more information.
