This Metasploit module uses the FreeSWITCH event socket interface to execute system commands using the system API command. The event socket service is enabled by default and listens on TCP port 8021 on the local network interface. This module has been tested successfully on FreeSWITCH versions: 1.6.10-17-726448d~44bit on FreeSWITCH-Deb8-TechPreview virtual machine; 1.8.4~64bit on Ubuntu 19.04 (x64); and 1.10.1~64bit on Windows 7 SP1 (EN) (x64).

This exploit uses the Cable Haunt vulnerability to open a shell for the Sagemcom F@ST 3890 (50_10_19-T1) cable modem. The exploit serves a website that sends a malicious websocket request to the cable modem. The request will overflow a return address in the spectrum analyzer of the cable modem and using a rop chain start listening for a tcp connection on port 1337. The server will then send a payload over this tcp connection and the modem will start executing the payload. The payload will listen for commands to be run in the eCos shell on the cable modem and redirect STDOUT to the tcp connection.
