CyberRota Analysis

AI-Generated

The vulnerability affects the WWBN AVideo platform, specifically in the AD_Server plugin's VMAP.php script, which allows for XML injection due to improper handling of user-supplied input. This flaw can be exploited by remote attackers to inject malicious ad content into video streams, leading to unauthorized ad injection and potential cross-origin request issues for users. Organizations using AVideo with the AD_Server plugin enabled should prioritize addressing this vulnerability to mitigate risks associated with ad fraud and user data exposure.

Original NVD Description

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.
