CVE-2024-54411: WP Controller CSRF Vulnerability

CVE-2024-54411 Overview

CVE-2024-54411 is a Cross-Site Request Forgery (CSRF) vulnerability in the hosting.io WP Controller plugin (wp-management-controller) for WordPress. The flaw affects all plugin versions up to and including 3.2.0. Attackers can chain the CSRF weakness with insufficient output encoding to achieve Stored Cross-Site Scripting (XSS). Successful exploitation requires a privileged user to interact with an attacker-controlled link or page while authenticated to the target WordPress site. The vulnerability is classified under CWE-352.

Critical Impact

An unauthenticated attacker can persist malicious JavaScript in the WordPress admin context by tricking an authenticated administrator into submitting a forged request, leading to session theft, account takeover, or further site compromise.

Affected Products

• hosting.io WP Controller plugin (wp-management-controller)
• All versions from initial release through 3.2.0
• WordPress installations with the plugin enabled

Technical Details for CVE-2024-54411

Vulnerability Analysis

The WP Controller plugin exposes state-changing endpoints that do not validate anti-CSRF tokens (WordPress nonces) before processing requests. An attacker hosts a crafted page containing a forged form or fetch request targeting the vulnerable endpoint. When an authenticated administrator visits that page, the browser automatically attaches the WordPress session cookies, and the plugin processes the request as if the administrator initiated it.

Because the affected endpoint also fails to sanitize and encode attacker-supplied input before storing or rendering it, the forged request injects JavaScript that persists in the database. The script then executes in the browser of any administrator who views the affected admin page, producing Stored XSS. The attack requires user interaction (UI:R) but no prior authentication on the attacker's side, and the scope changes because injected scripts execute under WordPress administrative privileges.

Root Cause

The root cause is the absence of CSRF protection on privileged actions, compounded by improper neutralization of input during web page generation. The plugin does not call wp_verify_nonce() (or an equivalent check) on the affected handlers and does not apply wp_kses(), esc_html(), or esc_attr() to user-controlled data before storage or output.

Attack Vector

Exploitation proceeds over the network. The attacker delivers a malicious link through phishing, a comment, or any channel that an administrator may click. The forged request silently posts attacker-controlled fields to the vulnerable plugin endpoint, which writes them into the database. The next administrator session that loads the affected admin view executes the injected payload.

No verified public proof-of-concept is currently available. See the Patchstack Vulnerability Report for the vendor disclosure.

Detection Methods for CVE-2024-54411

Indicators of Compromise

• Unexpected <script>, onerror, or onload content stored in WP Controller plugin options or post metadata
• WordPress administrator accounts created, modified, or elevated without a corresponding admin-initiated action
• HTTP POST requests to wp-management-controller endpoints with Referer headers pointing to external domains
• Outbound requests from administrator browsers to attacker-controlled hosts shortly after viewing plugin admin pages

Detection Strategies

• Inspect database tables (wp_options, wp_postmeta) for HTML or JavaScript content tied to the plugin's option keys.
• Enable WordPress audit logging to capture privileged actions triggered without an explicit admin navigation chain.
• Deploy a web application firewall rule that flags state-changing requests to plugin endpoints lacking a valid _wpnonce parameter.

Monitoring Recommendations

• Monitor administrator session telemetry for script execution patterns inconsistent with normal admin UI behavior.
• Alert on edits to plugin configuration originating from cross-origin referers.
• Track newly registered users, role changes, and plugin/theme installations following admin logins.

How to Mitigate CVE-2024-54411

Immediate Actions Required

• Update the WP Controller (wp-management-controller) plugin to a version released after 3.2.0 that addresses the CSRF flaw.
• If no fixed version is yet available, deactivate and remove the plugin until a patch is published.
• Force a password reset and session invalidation for all WordPress administrators on affected sites.
• Review stored plugin settings and posts for injected scripts and remove malicious payloads.

Patch Information

Review the Patchstack Vulnerability Report for vendor remediation status. Apply the latest plugin release once it becomes available and confirm the fix introduces nonce verification and proper output escaping.

Workarounds

• Restrict WordPress admin access by IP allowlist at the web server or WAF layer to reduce CSRF reachability.
• Enforce the SameSite=Lax or SameSite=Strict attribute on WordPress authentication cookies to limit cross-site cookie attachment.
• Require administrators to use a dedicated browser profile that is not used for general web browsing while managing the site.
• Deploy a Content Security Policy (CSP) for the WordPress admin interface to limit inline script execution.

# Example: block requests to the plugin endpoint that lack a valid nonce (nginx)
location ~* /wp-admin/admin-ajax.php {
    if ($arg_action ~* "wp-management-controller") {
        if ($arg__wpnonce = "") { return 403; }
    }
}
