<!--  
some notes about the exploit:  
  
- Tested working on a fully patched windows XP sp3 IE8 VM  
Last update was done on (Thursday, October 07, 2010)  
- Bad chars are: \x00\x80\x81\x82\x83\x84\x85\x86\x87\x88\x89\x8a\x8b\x8c\x8d\x8e  
\x8f\x90\x91\x92\x93\x94\x95\x96\x97\x98\x99\x9a\x9b\x9c\x9d\x9e\x9f  
- Offset to SEH is 2044 bytes in length  
- Warning, this exploit uses some static addresses from windows libraries and **may**  
not be reliable. It was tested reliably under my VM though.  
- Modules used do not have aslr enabled on XPsp3  
- VirtualProtect() had a bad char in it! (\x80) so we leak a ptr off the stack and calc offset  
- Not marked safe for scripting, but oh well :)  
- Built with love!  
  
shoutz to jduck for helping me with the msf module :-)
