CVE-2023-49490Public exploitNetwork attack vector

Administrator session theft via unescaped hidden inputs

Published Dec 11, 2023 · Updated Nov 26, 2024

Reflected XSS in /admin.php in XunRuiCMS 4.5.5 allows remote attackers to execute script in an administrator's browser via a crafted URL. The dr_form_search_hidden function concatenates unescaped s and other GET values into hidden input value attributes, allowing injected markup to become executable script. An administrator must visit the crafted link; script execution in that authenticated browser can disclose the administrator's session cookie.
