CVE-2019-5041
An exploitable Stack Based Buffer Overflow vulnerability exists in the EnumMetaInfo function of Aspose Aspose.Words for C++, version 18.11.0.0. A specially crafted doc file can cause a stack-based buffer overflow, resulting in remote code execution. An attacker needs to provide a malformed file to the victim to trigger this vulnerability.

CWE-121: Stack-based Buffer Overflow
This vulnerability is present in the Aspose.Words for C++ which is used for all kinds of operations related with DOC(X) files.
Aspose.Words library is used by many companies, banks, government organizations as a part of different software products responsible for data processing/conversion.
There is a vulnerability in the function responsible for handling meta info in a document. A specially crafted DOC file can lead to a stack-based buffer overflow and remote code execution.
Let’s investigate this vulnerability. After we attempt to create an instance of Aspose::Words::Document object, taking as a input malformed DOC file, we see the following state:
0:000> g

As we can see, the raised exception has a code 0xc00001a5, that is to say An invalid exception handler routine has been detected.. That state is also confirmed by the !exchain command, which shows that the SEH chain has been corrupted.
It can be a consequence of the stack-based buffer overflow which appeared before the exception was raised. Using the TTD functionality of windbgx, we can move backward to that moment before the SEH handler has been corrupted, landing inside the System::String::String constructor:

Line 35 memcpy(&_outString->strBeg, &inString->strBeg, 2 * v4);
The stack-based buffer overflow takes place exactly during the memcpy operation at line 35. The memcpy call is made with the following parameters:
0:000> dd esp L3
010feaf8 010feb72 010fec02 00000180
We can see that 0x180 bytes will be copied to the “buffer” pointed by 010feb72. Stepping back from the String constructor, we can see how much space has been “allocated” for dstString:
Line 1 void __thiscall sub_10812530(struct_v6 *this, char a2, _DWORD *a3, void *a4, int a5, int a6)

Line 17 strIndex = (struct_v9 *)bugyIndex;
Line 18 v16 = !v15 || _this->byte14 == 1 && !*_this->pdword1C;
Line 19 if ( v16 )
Line 20 {
Line 21 System::Detail::SmartPtrCounter::ThrowNullReferenceException(v13);
Line 22 v15 = (struct_v15 *)_this->pstruct_v718;
Line 23 }
Line 24 objStrCollection = v15->dword18;
Line 25 v18 = !objStrCollection || v15->byte14 == 1 && !*v15->pdword1C;
Line 26 if ( v18 )
Line 27 {
Line 28 System::Detail::SmartPtrCounter::ThrowNullReferenceException(objStrCollection);
Line 29 objStrCollection = v15->dword18;
Line 30 }
Line 31 System::Collections::Specialized::StringCollection::idx_get(objStrCollection, &srcString, strIndex);
Line 32
Line 33 v78 = operator new(0x60u);
Line 34 System::String::String((System::String *)&dstString, (const struct System::String *)&srcString);
At line 4 we see the dstString definition and its size, 0x44 bytes. Now it’s clear why the buffer overflow happens.
Let’s try to find out how and where srcString has been initialized. In line 31, the pointer to srcString is passed to the System::Collections::Specialized::StringCollection::idx_get method, where it will be initialized by an element from StringCollection. In our case strIndex has value 0xd2. Let’s step into System::Collections::Specialized::StringCollection::idx_get:
.text:0B129F00 ; System::String *__thiscall System::Collections::Specialized::StringCollection::idx_get(int thisStrCollection, System::String *outString, int index)
.text:0B129F00 public public: class System::String __thiscall System::Collections::Specialized::StringCollection::idx_get(int)const
.text:0B129F00 public: class System::String __thiscall System::Collections::Specialized::StringCollection::idx_get(int)const proc near
.text:0B129F00 ; DATA XREF: .rdata:off_D7534E8o
.text:0B129F00
.text:0B129F00 outString = dword ptr 4
.text:0B129F00 index = dword ptr 8
.text:0B129F00
.text:0B129F00 mov edx, [esp+index]
.text:0B129F04 mov eax, [ecx+8] ; objStrCollection ( 213ca7e0 )
.text:0B129F07 mov ecx, [esp+outString]
.text:0B129F0B shl edx, 4
.text:0B129F0E add edx, [esp+index]
.text:0B129F12 lea eax, [eax+edx*4]
.text:0B129F15 push eax ; struct System::String *
.text:0B129F16 call System::String::String(System::String const &)
.text:0B129F1B mov eax, [esp+outString]
.text:0B129F1F retn 8
.text:0B129F1F public: class System::String __thiscall System::Collections::Specialized::StringCollection::idx_get(int)const endp
We can see that the calculated address of an element is later passed to the String constructor. First, let’s examine a memory pointed by calculated element. Having EIP at address 0B129F16:
0:000> dd eax
213cdfa8 c0c0c0c0 c0c0c0c0 c0c0c0c0 c0c0c0c0
213cdfb8 c0c0c0c0 c0c0c0c0 c0c0c0c0 c0c0c0c0

213cdff8 c0c0c0c0 d0c0c0c0 ???????? ????????
213ce008 ???????? ???????? ???????? ????????
213ce018 ???????? ???????? ???????? ????????
The memory area is uninitialized (actually it is initialized, but by the heap allocator), and the outString/srcString object is initialized/constructed based on these values.
Let’s examine allocation size and capacity of objStrCollection:
0:000> !heap -p -a 213ca7e0

_DPH_HEAP_ROOT @ 15cd1000

So, there is space for:
0:000> ?382f / 0x44
Evaluate expression: 211 = 000000d3
0xd3 elements.
This means that we are still “in bounds” of the objStrCollection container, but that last element is not initialized.
Elements are added to that container by the function sub_1096FD60, via a call to the System::Collections::Specialized::StringCollection::Add method. The container is filled with data (strings) coming from a structure being located in the file around offset 0xB6D0.
The stack-based buffer overflow occurs because the application reaches to an element not being initialized in the container, which makes the iteration over this collection to depend on a different value than real container size. We discover the answer inside the function sub_108D9E60:
Line 1 int __usercall sub_108D9E60@<eax>(int cbData@<edx>, char *cbPlc@<ecx>, char a3, int a4, void *a5, char a6, int a7, void *a8, ...)
Line 2 {
Line 3
Line 4
Line 5 va_start(va, a8);
Line 6 v25 = cbData;
Line 7 v29 = cbPlc;
Line 8 v36 = 2;
Line 9 if ( cbPlc )
Line 10 {
Line 11 index_limit = (signed int)(cbPlc - 4) / (cbData + 4);
Line 12 if ( *sub_108D9D90() )
Line 13 {
Line 14 System::String::String(&v32, L"\nReading PLCF {0}, tableSize:{1}, structureSize:{2}, structureCount:{3}.", 72);
Line 15 v26 = 0;
Line 16 v27 = 0;
Line 17 LOBYTE(v36) = 4;
Line 18 v8 = System::String::ToU16Str(&v32, &v35);
Line 19 LOBYTE(v36) = 5;
Line 20 System::Details::FormatBuilder::FormatBuilder(&v33, v8, &v26);
Line 21 sub_FD17610(&v35);
Line 22 LOBYTE(v36) = 8;
Line 23 (...)
Line 24 }
Line 25 v29 = &v22;
Line 26 v22 = 0;
Line 27 sub_FD23BD0(&v22, &a6);
Line 28 LOBYTE(v36) = 9;
Line 29 sub_FD09890(&v19, (int)&a3, (int)&v19);
Line 30 LOBYTE(v36) = 2;
Line 31 sub_108DA100(index_limit,v19, v20, v21, v22, v23, v24);
It turns out that the value which controls the amount of iterations over objStrCollection is controlled by the index_limit variable. Its value is calculated based on cbPlc and cbData at line 11. More information about PLC structure we can find in documentation.
In our case, the value of an equation from the line 11 is equal to:
cbPLC = 0x92C
cbData = 4
so index_limit = 0x125.
That clearly explains why the uninitialized element is read from a collection, which consequently leads to a stack-based buffer overflow and can be turned by the attacker into remote code execution.
