CVE-2022-20828 is a vulnerability in the CLI parser of Cisco FirePOWER Software for Adaptive Security Appliance (ASA) FirePOWER module. It allows an authenticated, remote attacker with administrative access to execute arbitrary commands as root on the underlying operating system of the affected ASA FirePOWER module. The vulnerability is due to improper handling of undefined command parameters, which can be exploited via a crafted CLI command or a crafted HTTPS request to the web-based management interface.

This repository contains a single Metasploit module (modules/exploits/linux/http/cisco_asax_sfr_rce.rb) that exploits an authenticated command injection vulnerability (CVE-2022-20828) in Cisco ASA-X and ISA 3000 devices with FirePOWER Services. The exploit targets the ASDM web interface, requiring valid credentials, and injects commands into the SFR module's Linux VM as root. The module supports both simple shell payloads and full-featured Meterpreter sessions, allowing for extensive post-exploitation, including network pivoting and access to diverted network traffic. The exploit is weaponized, highly reliable, and leverages Metasploit's payload and session management features. The main attack vector is network-based, targeting the HTTPS ASDM management interface. The code is well-structured, with clear separation of check, exploit, and payload delivery logic, and is suitable for operational use by penetration testers or red teamers.
