umpnpmgr.dll - What is umpnpmgr.dll?
umpnpmgr.dll File Description:
Because of its utmost importance, the service cannot just be stopped at any given time once started. Any attempt to disable it poses a greater risk of making the system unusable. Much, in the same way, that the absence of the umpnpmgr.dll file would greatly affect the system's functions.
The code of the umpnpmgr.dll module dynamically linked a number of calls to wsprintfW to construct different formatted strings in stack buffers. This is applicable in instances where the user input is only validated by whether or not it matches a subkey of HKEY_LOCAL_MACHINE/ SYSTEM/ CurrentControlSet/ Enum.
Despite the fact that this registry branch is protected from unprivileged modifications, an assumption that any valid key name is safe can always be circumvented by adding arbitrary lengths of progressive backslashes; for example, "HTREE/ROOT////0////////" The functions PNP_GetDeviceList and PNP_GetDeviceListSize embedded in the umpnpmgr.dll module both exhibit this vulnerability.
As to the former, any valid subkey name may be accepted just to reach a vulnerable wsprintfW call, while the latter must receive a key name with an empty second or third component in order to reach a vulnerable wsprintfW call. This protective maneuver is due to the way SplitDeviceInstanceString patronizes the string.
This threat nonetheless is not related to the MS05-039 Plug and Play vulnerability and is not resolved by the MS05-039 hotfix. A generic security measure instituted in the patch will prevent its anonymous exploitation, making the eminent threat an internal healing or mass compromise in a domain setting.
Microsoft fixed this vulnerability in Windows 2003 by replacing the unsafe wsprintfW calls with calls to vsnwprintf. On why this security fix was not shipped to any other Windows operating system is yet to be given an explanation.Author: Microsoft Corporation
