Cisco IOX XE unauthenticated Command Line Interface (CLI) execution

Description

This module leverages CVE-2023-20198 against vulnerable instances of Cisco IOS XE devices which have the Web UI exposed. An attacker can execute arbitrary CLI commands with privilege level 15.

You must specify the IOS command mode to execute a CLI command in. Valid modes are `user`, `privileged`, and `global`. To run a command in "Privileged" mode, set the `CMD` option to the command you want to run, e.g. `show version` and set the `MODE` to `privileged`. To run a command in "Global Configuration" mode, set the `CMD` option to the command you want to run, e.g. `username hax0r privilege 15 password hax0r` and set the `MODE` to `global`.

The vulnerable IOS XE versions are: 16.1.1, 16.1.2, 16.1.3, 16.2.1, 16.2.2, 16.3.1, 16.3.2, 16.3.3, 16.3.1a, 16.3.4, 16.3.5, 16.3.5b, 16.3.6, 16.3.7, 16.3.8, 16.3.9, 16.3.10, 16.3.11, 16.4.1, 16.4.2, 16.4.3, 16.5.1, 16.5.1a, 16.5.1b, 16.5.2, 16.5.3, 16.6.1, 16.6.2, 16.6.3, 16.6.4, 16.6.5, 16.6.4s, 16.6.4a, 16.6.5a, 16.6.6, 16.6.5b, 16.6.7, 16.6.7a, 16.6.8, 16.6.9, 16.6.10, 16.7.1, 16.7.1a, 16.7.1b, 16.7.2, 16.7.3, 16.7.4, 16.8.1, 16.8.1a, 16.8.1b, 16.8.1s, 16.8.1c, 16.8.1d, 16.8.2, 16.8.1e, 16.8.3, 16.9.1, 16.9.2, 16.9.1a, 16.9.1b, 16.9.1s, 16.9.1c, 16.9.1d, 16.9.3, 16.9.2a, 16.9.2s, 16.9.3h, 16.9.4, 16.9.3s, 16.9.3a, 16.9.4c, 16.9.5, 16.9.5f, 16.9.6, 16.9.7, 16.9.8, 16.9.8a, 16.9.8b, 16.9.8c, 16.10.1, 16.10.1a, 16.10.1b, 16.10.1s, 16.10.1c, 16.10.1e, 16.10.1d, 16.10.2, 16.10.1f, 16.10.1g, 16.10.3, 16.11.1, 16.11.1a, 16.11.1b, 16.11.2, 16.11.1s, 16.11.1c, 16.12.1, 16.12.1s, 16.12.1a, 16.12.1c, 16.12.1w, 16.12.2, 16.12.1y, 16.12.2a, 16.12.3, 16.12.8, 16.12.2s, 16.12.1x, 16.12.1t, 16.12.2t, 16.12.4, 16.12.3s, 16.12.1z, 16.12.3a, 16.12.4a, 16.12.5, 16.12.6, 16.12.1z1, 16.12.5a, 16.12.5b, 16.12.1z2, 16.12.6a, 16.12.7, 16.12.9, 16.12.10, 17.1.1, 17.1.1a, 17.1.1s, 17.1.2, 17.1.1t, 17.1.3, 17.2.1, 17.2.1r, 17.2.1a, 17.2.1v, 17.2.2, 17.2.3, 17.3.1, 17.3.2, 17.3.3, 17.3.1a, 17.3.1w, 17.3.2a, 17.3.1x, 17.3.1z, 17.3.3a, 17.3.4, 17.3.5, 17.3.4a, 17.3.6, 17.3.4b, 17.3.4c, 17.3.5a, 17.3.5b, 17.3.7, 17.3.8, 17.4.1, 17.4.2, 17.4.1a, 17.4.1b, 17.4.1c, 17.4.2a, 17.5.1, 17.5.1a, 17.5.1b, 17.5.1c, 17.6.1, 17.6.2, 17.6.1w, 17.6.1a, 17.6.1x, 17.6.3, 17.6.1y, 17.6.1z, 17.6.3a, 17.6.4, 17.6.1z1, 17.6.5, 17.6.6, 17.7.1, 17.7.1a, 17.7.1b, 17.7.2, 17.10.1, 17.10.1a, 17.10.1b, 17.8.1, 17.8.1a, 17.9.1, 17.9.1w, 17.9.2, 17.9.1a, 17.9.1x, 17.9.1y, 17.9.3, 17.9.2a, 17.9.1x1, 17.9.3a, 17.9.4, 17.9.1y1, 17.11.1, 17.11.1a, 17.12.1, 17.12.1a, 17.11.99SW
