The script emits Content-Type: application\/xml and writes the timeOffset and idTag values returned by AD_Server::getVMAPSFromRequest() directly into VMAP attributes without encoding. Those values originate from the base64- and JSON-decoded $_REQUEST[&#8216;vmaps&#8217;] parameter, which is not covered by $securityFilter in objects\/security.php. A remote attacker can craft a vmaps value (containing a non-empty VAST.campaing entry) and induce a user to open the resulting VMAP URL or a video page using it, injecting arbitrary  and \/AdSource nodes into the generated XML. The player&#8217;s IMA path (afterVideoJS -&gt; PlayerSkins::setIMAADTag) then requests the attacker-supplied ad URLs, resulting in ad injection and cross-origin requests from the victim&#8217;s playback session.
