HTTP: Script Evasion Function Reassignment

This signature detects attempts to exploit a known JavaScript/VBScript evasion technique. Many common Web browsers and servers are affected. The technique utilizes function reassignment, which if successful, enables the malicious script to bypass name filtering systems.

Extended Description

Internet Explorer is prone to a remote code-execution vulnerability. Attackers can exploit this issue to execute arbitrary code in the context of the user running the browser. Successful exploits will compromise the application and possibly the computer. Failed attacks will cause denial-of-service conditions.
