Description
The vulnerability allows a remote user to execute arbitrary script in the victim's browser.
The vulnerability exists due to cross-site scripting in the EPG page when rendering program titles from user-controlled XML content. A remote user can set a video's epg_link to a malicious XML file containing crafted program titles to execute arbitrary script in the victim's browser.
User interaction is required to visit the public EPG page, and the malicious content may persist due to server-side caching.
