MS11-021 Microsoft Office 2007 Excel .xlb Buffer Overflow

Posted on 07 November 2011

This Metasploit module exploits a vulnerability found in Excel of Microsoft Office 2007. By supplying a malformed .xlb file, an attacker can control the content (source) of a memcpy routine, and the number of bytes to copy, therefore causing a stack-based buffer overflow. This results in arbitrary code execution under the context of the user.
