概要
WWBN AVideo Vulnerable to stored XSS via Unanchored Duration Regex in Video Encoder Receiver
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
WWBN AVideo is an open source video platform. In versions 29.0 and below, the isValidDuration() regex at objects/video.php:918 uses /^[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2}/ without a $ end anchor, allowing arbitrary HTML/JavaScript to be appended after a valid duration prefix. The crafted duration is stored in the database and rendered without HTML escaping via echo Video::getCleanDuration() on trending pages, playlist pages, and video gallery thumbnails, resulting in stored cross-site scripting. Commit bcba324644df8b4ed1f891462455f1cd26822a45 contains a fix.
