CVE-2024-8268: Buffercode Frontend Dashboard RCE Flaw

CVE-2024-8268 Overview

CVE-2024-8268 affects the Frontend Dashboard plugin for WordPress, developed by Buffercode. The vulnerability exists in all versions up to and including 2.2.4. It stems from insufficient filtering on callable methods and functions within the ajax_request() function. Authenticated attackers with subscriber-level access or higher can invoke arbitrary PHP functions on the affected site. Attackers can leverage this to change other users' passwords and escalate privileges to administrator. The issue is tracked under CWE-94: Improper Control of Generation of Code.

Critical Impact
Authenticated subscribers can execute arbitrary WordPress functions, reset passwords of privileged accounts, and take over affected WordPress sites.

Affected Products

Buffercode Frontend Dashboard plugin for WordPress, all versions through 2.2.4
WordPress sites permitting subscriber-level registration with the plugin enabled
Fixed release: Frontend Dashboard 2.2.5

Technical Details for CVE-2024-8268

Vulnerability Analysis

The Frontend Dashboard plugin exposes an AJAX endpoint handled by the ajax_request() function in route/class-fed-request.php. The handler dispatches user-supplied input to callable PHP functions and methods without a strict allow-list. Because the plugin accepts arbitrary function names from client input, attackers can pivot the AJAX endpoint into a generic function-invocation primitive. Successful exploitation lets a low-privileged user call sensitive WordPress core functions such as wp_set_password or wp_update_user, resulting in account takeover of administrators.

Root Cause

The root cause is improper control of code generation, classified as CWE-94. The vulnerable dispatcher in the 2.2.4 tag of class-fed-request.php does not validate the requested callable against an allow-list of intended plugin methods. Any function name reachable in the PHP runtime becomes an execution target. The vendor addressed this in changeset 3147868 by restricting callable targets in version 2.2.5.

Attack Vector

The attack is delivered over the network against the WordPress AJAX endpoint. An attacker first registers or holds any account at subscriber level or above, which is trivial on sites that permit open registration. The attacker then issues an authenticated AJAX POST to the plugin's request handler, specifying a target function name and its arguments. By invoking wp_set_password against an administrator user ID, the attacker resets the target's credential and logs in as that administrator.

Detection Methods for CVE-2024-8268

Indicators of Compromise

Unexpected password reset events for administrator accounts, followed by logins from unfamiliar IP addresses or user agents
New administrator-role accounts created by low-privileged users shortly after AJAX activity to the Frontend Dashboard endpoint
POST requests to admin-ajax.php or the plugin's fed-request route containing parameters that reference WordPress core functions such as wp_set_password, wp_update_user, or wp_create_user
Frontend Dashboard plugin version reported as 2.2.4 or earlier in wp-content/plugins/frontend-dashboard/

Detection Strategies

Inspect web server access logs for authenticated AJAX requests to the Frontend Dashboard handler that include function-name parameters not associated with normal dashboard usage
Correlate WordPress audit-log events for password resets and role changes with the source session and originating IP address
Alert on subscriber-role sessions triggering privilege changes or user metadata updates within a short time window

Monitoring Recommendations

Enable a WordPress activity log plugin to record authentication, password change, and role change events for later review
Forward WordPress and web server logs into a centralized SIEM so plugin-specific patterns can be searched and retained
Monitor for post-exploitation behaviors on the underlying host, including PHP process anomalies, webshell drops under wp-content/uploads, and outbound connections to unknown infrastructure

How to Mitigate CVE-2024-8268

Immediate Actions Required

Update the Frontend Dashboard plugin to version 2.2.5 or later on every affected WordPress site
Audit administrator and editor accounts for unexpected members, recent password resets, or email address changes and revoke or reset any suspicious accounts
Disable open user registration or restrict the default new-user role until patching is complete and account review is finished
Rotate credentials for all privileged WordPress users and invalidate active sessions after patching

Patch Information

The vendor released Frontend Dashboard 2.2.5, which restricts callable targets in the AJAX request handler. Details of the code change are available in the WordPress Plugin Changeset 3147868. Site operators should verify the installed version reports 2.2.5 or later after the update.

Workarounds

If immediate patching is not possible, deactivate and remove the Frontend Dashboard plugin until the update can be applied
Block unauthenticated and subscriber-level access to the plugin's AJAX route at the web application firewall (WAF) or reverse proxy layer
Temporarily set users_can_register to false in WordPress general settings to prevent attackers from self-provisioning subscriber accounts

bash

# Update Frontend Dashboard via WP-CLI and verify the installed version
wp plugin update frontend-dashboard --version=2.2.5
wp plugin get frontend-dashboard --field=version

# Disable open registration as a temporary hardening step
wp option update users_can_register 0
