Name of the Vulnerable Software and Affected Versions zzcms version 2019

Description The issue is related to a Cross-Site Scripting (XSS) vulnerability in the user login page. Users can inject JavaScript code through the referer header via the "user/login.php" endpoint. This allows attackers to execute malicious scripts on the client-side.

Recommendations For zzcms version 2019, as a temporary workaround, consider restricting access to the "user/login.php" endpoint until a patch is available. Additionally, avoid using the referer header in the login process to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
