A server-side request forgery (SSRF) vulnerability exists in the VidiU management interface within the RTMP settings and the Wowza server mode functionality. The application parses user supplied data in the GET parameters 'url' and 'xml_url' to construct a page request that loads the configuration for specific service. Since no validation is carried out on the parameters, an attacker can specify an external domain and force the application to make a HTTP request to an arbitrary destination host, including xml data parsing (XXE potential). This can be used by an external attacker for example to bypass firewalls and initiate a service and network enumeration on the internal network through the affected application.
