Risk
High
Date Discovered
July 10, 2012
Description
Microsoft Windows is prone to a remote command-injection that affects the Windows Shell component vulnerability because it fails to adequately sanitize user-supplied input data.
Attackers can exploit this issue to execute arbitrary shell commands with user-level privileges. This may facilitate the remote compromise of affected computers.
Recommendations
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 including unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.Run all software as a nonprivileged user with minimal access rights.
To limit the potential damage that successful exploits may achieve, run all nonadminstrative software as a nonadministrative user.Do not accept or execute files from untrusted or unknown sources.
Users should never accept files from untrusted or
unknown sources, because they may be malicious in nature. Avoid opening email attachments from unknown or
questionable sources.Do not follow links provided by unknown or untrusted sources.
To reduce the likelihood of successful exploits, never visit sites of questionable integrity or follow links provided by
unfamiliar or untrusted sources.
Updates are available. Please see the references for more information.
