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.
