Summary

Zenar Content Management System contains a cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious scripts by manipulating form parameters in POST requests. Attackers can inject script tags through the current_page parameter sent to the ajax.php endpoint, which reflects unsanitized user input in the response HTML to execute arbitrary JavaScript in victim browsers.
