Nvidia (nvsvc) Display Driver Service Local Privilege Escalation
Description
The named pipe, \pipe\nsvr, has a NULL DACL allowing any authenticated user to interact with the service. It contains a stacked based buffer overflow as a result of a memmove operation. Note the slight spelling differences: the executable is 'nvvsvc.exe', the service name is 'nvsvc', and the named pipe is 'nsvr'. This exploit automatically targets nvvsvc.exe versions dated Nov 3 2011, Aug 30 2012, and Dec 1 2012. It has been tested on Windows 7 64-bit against nvvsvc.exe dated Dec 1 2012.

- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
