NPS Datastore server DLL side loading vulnerability
------------------------------------------------------------------------
Yorick Koster, September 2015

Abstract
------------------------------------------------------------------------
A DLL side loading vulnerability was found in the NPS Datastore server
DLL that ships with Windows Vista. This issue can be exploited by
loading the affected DLL as an embedded OLE object. When instantiating
the object Windows will try to load the DLL iasdatastore2.dll from the
current working directory. If an attacker convinces the user to open a
specially crafted (Office) document from a directory also containing the
attacker's DLL file, it is possible to execute arbitrary code with the
privileges of the target user. This can potentially result in the
attacker taking complete control of the affected system.
