Microsoft Windows Search Script Injection Vulnerability

Risk

Medium

Date Discovered

June 9, 2009

Description

Microsoft Windows Search is prone to a script-injection vulnerability because it fails to adequately sanitize user-supplied input when previewing search results. Successful exploits will cause malicious script code to run in the local context, allowing attackers to steal potentially sensitive information or perform other attacks. The issue affects Windows Search installed on all supported editions of Windows XP and Windows Server 2003. Note that Windows Vista and Windows Server 2008 are not affected.

Technologies Affected

  • Microsoft Windows Search 4.0

Recommendations

Run all software as a nonprivileged user with minimal access rights.

To limit the potential damage that successful exploits may achieve, run all nonadministrative software as an unprivileged user.

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 may indicate exploit attempts or activity that results from successful exploits.

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.
The vendor has released an advisory and fixes. Please see the references for details.
