Exploitation Summary

EIP tracks 1 public exploit for CVE-2018-19911. PoCs published by iSafeBlue.

AI-analyzed exploit summary This PoC exploits an authentication bypass and command injection vulnerability in FreeSWITCH's API endpoints. It sends a reverse shell payload via multiple API paths to achieve remote code execution.

Description

FreeSWITCH through 1.8.2, when mod_xml_rpc is enabled, allows remote attackers to execute arbitrary commands via the api/system or txtapi/system (or api/bg_system or txtapi/bg_system) query string on TCP port 8080, as demonstrated by an api/system?calc URI. This can also be exploited via CSRF. Alternatively, the default password of works for the freeswitch account can sometimes be used.
