Admin Custom Login <= 3.6.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'Message Above Login Form' Setting

Admin Custom Login <= 3.6.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'Message Above Login Form' Setting

The Admin Custom Login plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.6.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
Mögliche Gegenmaßnahme
Admin Custom Login: Update to version 3.6.5, or a newer patched version
