SafeSEH+SEHOP all-at-once bypass explotation method principles

2012-01-12 Thread geinblues
Hello, I wrote this to introduce a small paper for my exploitation method of SafeSEH+SEHOP bypass in Oct, 2010. (http://www.x90c.org/SEH all-at-once attack.pdf, http://www.exploit-db.com/exploits/15184) Sadly it's not portable. But leave some thoughts about the method. - SafeSEH+SEHOP

Another new technique to bypass SEHOP. ( no 'xor pop pop ret' )

2010-10-04 Thread geinblues
Lately, MS Windows SEH overflow attack technique only uses the methods. [mostly used method] win xp sp2(SEH): 'pop pop ret' - David Litchfield 2003. win xp sp3(SafeSEH): unloaded module's 'pop pop ret' - Litchfield 2003. win server 2008/Vista sp1(SEHOP): SYSDREAM(c)'s 'xor pop pop ret'.
