This Metasploit module exploits a vulnerability found in Internet Explorer's mshtml component. Due to the way IE handles objects in memory, it is possible to cause a pointer in CTableRowCellsCollectionCacheItem::GetNext to be used even after it gets freed, therefore allowing remote code execution under the context of the user. This particular vulnerability was also one of 2012's Pwn2Own challenges, and was later explained by Peter Vreugdenhil with exploitation details. Instead of Peter's method, this module uses heap spraying like the 99% to store a specially crafted memory layout before re-using the freed memory.

User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the handling of cloned DOM objects in JavaScript. A specially crafted sequence of object cloning can result in the use of a pointer after it has been freed. Successful exploitation can lead to remote system compromise under the credentials of the currently logged in user.
