Title
WWBN AVideo XML Injection via plugin/AD_Server/VMAP.php
Summary
WWBN AVideo at commit c3edcc274c389816d434acadac07ee78eaf330c1 and earlier contains an XML injection vulnerability in plugin/AD_Server/VMAP.php, which is reachable without authentication when the AD_Server plugin is enabled. 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['vmaps'] 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 <vmap:AdBreak> and <vmap:AdTagURI>/AdSource nodes into the generated XML. The player's IMA path (afterVideoJS -> PlayerSkins::setIMAADTag) then requests the attacker-supplied ad URLs, resulting in ad injection and cross-origin requests from the victim's playback session. The issue was unfixed at the time of reporting.

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[\u0027vmaps\u0027] 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 \u003cvmap:AdBreak\u003e and \u003cvmap:AdTagURI\u003e/AdSource nodes into the generated XML. The player\u0027s IMA path (afterVideoJS -\u003e PlayerSkins::setIMAADTag) then requests the attacker-supplied ad URLs, resulting in ad injection and cross-origin requests from the victim\u0027s playback session. The issue was unfixed at the time of reporting."
