Description

This module exploits a command injection vulnerability in IBM AIX invscout set-uid root utility present in AIX 7.2 and earlier. The undocumented -rpm argument can be used to install an RPM file; and the undocumented -o argument passes arguments to the rpm utility without validation, leading to command injection with effective-uid root privileges. This module has been tested successfully on AIX 7.2.

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.
