The creation of the exploit (especially as it relates to exploit mitigation RCX, RDX, R8 and R9) no stack pivot is needed, and this drastically simplifies Since it is on 64-bit (the first 4 parameters are in Ret2libc style attack with a RIP hijack to NTDLL.DLL!NtContinue which thenĬalls KERNE元2.DLL!WinExec. Maxspl0it's variation of this exploit works on IE 8-11 64-bit. The original public 64-bit variation of this exploit was written by maxspl0it ![]() Of Internet Explorer but its load/usage can still be coerced (and thus exploited)Ī high quality description of this exploit can be found on F-Secure's blog at: Javascript engine (jscript.dll) in Windows. ![]() ![]() This is a 32-bit re-creation of CVE-2020-067, a vulnerability in the legacy # Original (64-bit) exploit credits: maxpl0it # Bypasses: DEP, ASLR, EMET 5.5 (EAF, EAF+, stack pivot protection, SimExec, CallerCheck) # Tested on: Windows 7 圆4 and Windows 7 x86 # Exploit Title: Microsoft Internet Explorer 11 32-bit - Use-After-Free
