Detailed vulnerability 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.
