id: CVE-2023-5089
info:
name: WordPress Defender Security Plugin - Hidden Login Bypass
name: Defender Security < 4.1.0 - Protection Bypass (Hidden Login Page)
author: jpg0mez
severity: low
severity: medium
description: |
The Defender Security WordPress plugin before 4.1.0 does not prevent redirects to the login page via the auth_redirect WordPress function,
allowing an unauthenticated visitor to access the login page, even when the hide login page functionality of the plugin is enabled.
-----IMPORTANT------
Note: This PoC calls the auth_redirect function via GravityForms (gf_page). Most WordPress plugins that hide the login page are vulnerable
to this, so be sure to confirm the target is using WP-Defender.
remediation: |
Upgrade to the latest version to mitigate this vulnerability.
The Defender Security WordPress plugin before 4.1.0 does not
prevent redirects to the login page via the auth_redirect WordPress
function, allowing an unauthenticated visitor to access the login page, even
when the hide login page functionality of the plugin is enabled.
remediation: Fixed in 4.1.0
