## Description

This module examines the sudoers configuration for the session user
and lists the commands executable via `sudo`.

This module also inspects each command and reports potential avenues
for privileged code execution due to poor file system permissions or
permitting execution of executables known to be useful for privesc,
such as utilities designed for file read/write, user modification,
or execution of arbitrary operating system commands.

Note, you may need to provide the password for the session user.


## Verification Steps

1. Start `msfconsole`
2. Get a session
3. `use post/multi/recon/sudo_commands`
4. `set SESSION [SESSION]`
5. `run`
6. You should receive a list of available `sudo` commands


## Options

**SESSION**

Which session to use, which can be viewed with `sessions`

**SUDO_PATH**

Path to sudo executable (default: `/usr/bin/sudo`)

**PASSWORD**

Password for the session user


## Scenarios

```
msf5 > use post/multi/recon/sudo_commands
msf5 post(multi/recon/sudo_commands) > set session 1
session => 1
msf5 post(multi/recon/sudo_commands) > set verbose true
verbose => true
msf5 post(multi/recon/sudo_commands) > run
