Description

This module attempts to gain root privileges by exploiting a vulnerability in ktsuss versions 1.4 and prior. The ktsuss executable is setuid root and does not drop privileges prior to executing user specified commands, resulting in command execution with root privileges. This module has been tested successfully on: ktsuss 1.3 on SparkyLinux 6 (2019.08) (LXQT) (x64); and ktsuss 1.3 on SparkyLinux 5.8 (LXQT) (x64).

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.
