It is possible for an attacker to execute a DLL planting attack in Microsoft Office 2010 on Windows 7 x86 with a specially crafted OLE object. The attached POC document "planted-mfplat.doc" contains what was originally an embedded Packager object. The CLSID for this object was changed at offset 0x2650 to be {62dc1a93-ae24-464c-a43e-452f824c4250} (formatted as pack(">IHHBBBBBBBB")) which is one of several registered objects that have an InProcServer32 of WMALFXGFXDSP.dll. Other options include:
|
|
|
|
{637c490d-eee3-4c0a-973f-371958802da2}
|
|
{874131cb-4ecc-443b-8948-746b89595d20}
|
|
{96749377-3391-11D2-9EE3-00C04F797396}
|
|
|
|
When a user opens this document and single clicks on the icon for foo.txt ole32!OleLoad is invoked on our vulnerable CLSID. This results in a call to wmalfxgfxdsp!DllGetClassObject() which does a LoadLibraryW() call for "mfplat". If the attached mfplat.dll is placed in the same directory with the planted-mfplat.doc file you should see a popup coming from this DLL being loaded from the current working directory of Word.

Here is the call stack leading up to the vulnerable LoadLibraryW() call:
