CyberRota Analysis

AI-Generated

The vulnerability affects the AVideo platform, specifically in the `confirmLivePassword.php` script, which improperly handles an unauthenticated GET parameter, allowing for reflected cross-site scripting (XSS) attacks. A remote attacker can exploit this flaw to execute arbitrary JavaScript in the context of the site, potentially compromising user accounts, including those of administrators. Organizations using AVideo should prioritize remediation to protect against potential exploitation, particularly if they have users with elevated privileges.

Original NVD Description

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in plugin/Live/confirmLivePassword.php. The script interpolates the unauthenticated GET parameter u (which is not covered by $securityFilter) directly into an <img src="..."> attribute without URL- or HTML-encoding. A remote attacker can craft a link containing a double-quote character in u (with a non-empty key parameter and no valid c parameter) to close the src attribute and inject an additional tag with an onerror handler, executing arbitrary JavaScript in the site's origin in the browser of any user, including an administrator, who opens the link. No patched version was available at the time of the advisory.
