Technical details
A reflected cross-site scripting (XSS) vulnerability exists in SVXportal versions 2.5 and earlier. The vulnerability is located in the 'log.php' component, where the 'search' query parameter is embedded directly into an HTML input value attribute without proper sanitization. An unauthenticated remote attacker can exploit this by inducing a user to visit a specially crafted URL. Successful exploitation allows the execution of arbitrary JavaScript in the context of the victim's browser session, which can be used to capture session cookies or perform actions on behalf of the user. As of the advisory date, users are advised to check for updates or manually sanitize input in log.php.
