Description

This module exploits a vulnerability in a statement in the system programming guide of the Intel 64 and IA-32 architectures software developer's manual being mishandled in various operating system kerneles, resulting in unexpected behavior for #DB excpetions that are deferred by MOV SS or POP SS. This module will upload the pre-compiled exploit and use it to execute the final payload in order to gain remote code execution.

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/mov_ss
msf exploit(mov_ss) > show targets
    ...targets...
msf exploit(mov_ss) > set TARGET < target-id >
msf exploit(mov_ss) > show options
    ...show and set options...
msf exploit(mov_ss) > 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.
