CyberRota Analysis

AI-Generated

The AVideo platform's AD_Server plugin is vulnerable to a stored cross-site scripting (XSS) flaw in the log.php endpoint, where the label parameter is improperly sanitized before being stored. This allows unauthenticated attackers to inject malicious HTML, which can execute arbitrary JavaScript in an administrator's browser session when viewed in the Ad Types report. Organizations using AVideo should prioritize patching this vulnerability to protect against potential exploitation that could compromise admin accounts.

Original NVD Description

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the AD_Server plugin's log.php endpoint that fails to escape the label parameter before storage. An unauthenticated attacker can inject malicious HTML through the label parameter, which is later rendered unsanitized in the admin Ad Types report using jQuery .html(), allowing execution of arbitrary JavaScript in an administrator's browser session.
