Signature Detail

HTTP: Internet Explorer createControlRange Invalid Object Type

This signature detects attempts to exploit a known DHTML input validation vulnerability in Microsoft Internet Explorer. Attackers can create a malicious Web page that, when viewed by a user, causes a heap overflow and executes arbitrary code on the target system.

Extended Description

Microsoft Internet Explorer is prone to a heap-based buffer-overflow vulnerability caused by a boundary condition error that is exposed when passing data to the 'createControlRange()' DHTML method. As a result, heap-based memory can be corrupted with attacker-supplied data. An attacker could exploit this issue to execute arbitrary code in the context of the currently logged-in user.
