The “internet explorer 11 for windows 7 32-bit offline installer” is a download that allows users to install Internet Explorer 11 without the need for an internet connection. It was designed to be faster than IE 9, which has been criticized as slower on some devices like tablets or computers with multiple cores. It was released by Microsoft in September 2014 for Windows 7, 8 and 10 operating systems. Return (MutableVar.length > 15) & 0xff // Shift to align and get the byte. ReClaimNameList(0, CreateVar64(0x8, Address.low + 2, Address.high, 0, 0)) // +2 for BSTR length adjustment (only a WORD at a time can be cleanly read despite being a 32-bit field) NextPtrLow & 0xffff, (NextPtrLow > 16) & 0xffff, NextPtrHigh & 0xffff, (NextPtrHigh > 16) & 0xffff) SortArray.sort(GlitchedComparator) įor(var i = 0 i > 16) & 0xffff, ObjPtrHigh & 0xffff, (ObjPtrHigh > 16) & 0xffff, This try/catch in conjunction with a global initialization of the sort array allows the depth to be sufficient to produce an untracked var which will overlap with the type confusion offset in the re-claimed GcBlock. In IE, a stack overflow exception will occur around depth 250 however in WPAD it will occur on a depth of less than 150, ensuring a stack overflow exception/alert will be thrown in the exploit. There is a difference between the stack size between WPAD and Internet Explorer. VarSpray = new Array() // Erase references to sprayed vars within GcBlocks
R9 = Leaked address of BSTR to hold out param NTDLL.DLL!NtContinue -> RIP = | MOV RSP, R11 RET Through use of NTDLL.DLL!NtContinue, an artificial stack (built on the heap)Īnd a dynamically resolved stack pivot ROP gadget. On a user defined shellcode stored within a BSTR on the heap. Ultimately the exploit aims to use KERNE元2.DLL!VirtualProtect to disable DEP References in the runtime script is then used for arbitrary read (via BSTR) Control of the memory of VAR structs with active JS var The UAF is a result of two untracked variables passed to a comparator for theĪrray.sort method, which can then be used to reference VAR structs withinĪllocated GcBlock regions which can subsequently be freed via garbageĬollection.

This is a 64-bit adaptation of CVE-2020-0674 which can exploit both IE8/11Ħ4-bit as well as the WPAD service on Windows 7 and 8.1 圆4. |_| |_| | WPAD sandbox escape | -> | svchost.exe | | firefox.exe | -> | svchost.exe | -> | spoolsv.exe |
