CVE-2024-54307: AIcomments Plugin CSRF Vulnerability

CVE-2024-54307 Overview

CVE-2024-54307 is a Cross-Site Request Forgery (CSRF) vulnerability in the aipost AIcomments WordPress plugin. The flaw affects all plugin versions up to and including 1.4.1. An attacker can trick an authenticated user into submitting a forged request that performs state-changing actions inside the plugin without consent. The weakness is classified under CWE-352: Cross-Site Request Forgery. Exploitation requires user interaction, typically by luring a logged-in user to a malicious page or link.

Critical Impact
Successful exploitation allows attackers to perform unauthorized state-changing actions in the AIcomments plugin using the privileges of an authenticated WordPress user.

Affected Products

aipost AIcomments WordPress plugin versions through 1.4.1
WordPress sites with the AIcomments plugin installed and active
Any environment allowing authenticated user sessions with the vulnerable plugin

Technical Details for CVE-2024-54307

Vulnerability Analysis

The AIcomments plugin exposes one or more action handlers that accept requests without validating a CSRF token or verifying request origin. WordPress plugins typically defend against CSRF by requiring a nonce generated with wp_create_nonce() and verified with check_admin_referer() or wp_verify_nonce(). AIcomments through version 1.4.1 fails to enforce this check on privileged endpoints.

An attacker who hosts a malicious page can craft an HTML form or JavaScript request that targets the vulnerable plugin endpoint. When an authenticated site user visits the page, the browser attaches valid session cookies, and the plugin processes the request as legitimate. Attack complexity is low and no authentication is required from the attacker, though user interaction is needed.

Root Cause

The root cause is missing or improper anti-CSRF token validation on plugin request handlers. Without a nonce check, the plugin cannot distinguish between requests initiated by the authenticated user and requests triggered by third-party origins.

Attack Vector

The attack vector is network-based and exploited over HTTP. An attacker delivers a crafted link, embedded image, or auto-submitting form to a WordPress user with an active session on the target site. The vulnerable plugin executes the forged request, altering plugin state or performing actions on behalf of the victim. Confidentiality is not affected, but integrity of plugin-managed data can be modified.

Detection Methods for CVE-2024-54307

Indicators of Compromise

Unexpected changes to AIcomments plugin configuration or comment data without corresponding admin activity in audit logs
HTTP POST requests to AIcomments plugin endpoints with Referer or Origin headers pointing to external domains
Access log entries showing state-changing plugin requests immediately following a user visit to an external site

Detection Strategies

Inspect WordPress access logs for requests to AIcomments plugin handlers that lack a valid _wpnonce parameter
Correlate cross-origin Referer headers with successful plugin state changes in application logs
Deploy a Web Application Firewall (WAF) rule that flags POST requests to /wp-admin/admin-ajax.php or plugin URIs missing nonce parameters

Monitoring Recommendations

Enable WordPress audit logging plugins to record all administrative and plugin configuration changes
Monitor for anomalous browser-driven requests originating from user sessions shortly after external site visits
Alert on any modifications to AIcomments settings outside of expected administrative maintenance windows

How to Mitigate CVE-2024-54307

Immediate Actions Required

Update the AIcomments plugin to a version later than 1.4.1 once the vendor publishes a fixed release
Deactivate and remove the AIcomments plugin if a patched version is not yet available
Instruct WordPress users with elevated privileges to log out of admin sessions when browsing untrusted sites

Patch Information

At the time of publication, no fixed version is referenced in the NVD entry for CVE-2024-54307. Monitor the Patchstack advisory and the plugin repository for release of a patched version that adds nonce verification to affected handlers.

Workarounds

Restrict access to /wp-admin/ using IP allow-listing at the web server or reverse proxy
Configure a WAF to require the Referer header match the site origin for plugin state-changing endpoints
Enforce short session lifetimes for WordPress administrator accounts to shrink the exploitation window

bash

# Example nginx configuration to block cross-origin POST requests to admin-ajax
location = /wp-admin/admin-ajax.php {
    if ($request_method = POST) {
        set $block 1;
    }
    if ($http_referer ~* "^https?://your-wordpress-site\.com") {
        set $block 0;
    }
    if ($block = 1) {
        return 403;
    }
}
