Signature Detail

HTTP: HTML Help Local Code Execution

This signature detects attempts to exploit a known vulnerability in the Help Center ActiveX control. A remote attacker can use the Help Center to write arbitrary script commands to the local zone, than exploit the zone to download arbitrary content to the startup folder. When the host reboots, the arbitrary content is executed, potentially compromising the system.

Extended Description

The ActiveX control that provides much of the functionality for the Windows Help Center contains an unchecked buffer. Successful exploitation could result in execution of arbitrary code in the security context of the current user.
