Mac OS X NFS Mount Privilege Escalation Exploit
Description
This exploit leverages a stack buffer overflow vulnerability to escalate privileges. The vulnerable function nfs_convert_old_nfs_args does not verify the size of a user-provided argument before copying it to the stack. As a result, by passing a large size as an argument, a local user can overwrite the stack with arbitrary content. Mac OS X Lion Kernel <= xnu-1699.32.7 except xnu-1699.24.8 are affected.

- 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.
