⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could access sensitive internal services (like databases, admin panels), perform port scanning of internal networks, or use the server as a proxy for attacks against other systems.

🟠

Likely Case

Information disclosure from internal services, reconnaissance of internal network structure, or abuse of server resources for scanning external targets.

🟢

If Mitigated

Limited to unsuccessful connection attempts or requests to non-sensitive endpoints if proper network segmentation and firewall rules are in place.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires sending crafted requests to the mxchat_handle_chat_request AJAX endpoint with malicious URLs in PDF processing functionality.

🔧 Temporary Workarounds

Disable vulnerable AJAX endpoint

WordPress

Remove or restrict access to the mxchat_handle_chat_request AJAX action

Add to theme's functions.php or custom plugin:
add_action('init', function() {
    remove_action('wp_ajax_mxchat_handle_chat_request', 'mxchat_handle_chat_request');
    remove_action('wp_ajax_nopriv_mxchat_handle_chat_request', 'mxchat_handle_chat_request');
});

Web Application Firewall rule

all

Block requests containing SSRF patterns to the vulnerable endpoint

WAF rule to block: POST requests to /wp-admin/admin-ajax.php with 'action=mxchat_handle_chat_request' and URL parameters containing internal IP addresses or localhost references

🧯 If You Can't Patch

  • Disable the MxChat plugin completely until patched
  • Implement strict outbound firewall rules to limit server's ability to connect to internal networks

🔍 How to Verify

Check if Vulnerable:

Check WordPress admin → Plugins → MxChat version. If version is 2.4.6 or lower, you are vulnerable.

Check Version:

wp plugin list --name=mxchat-basic --field=version

Verify Fix Applied:

After updating, verify plugin version shows 2.4.7 or higher in WordPress admin panel.

📡 Detection & Monitoring

Log Indicators:

  • Multiple POST requests to /wp-admin/admin-ajax.php with action=mxchat_handle_chat_request
  • Unusual outbound connections from WordPress server to internal IP ranges
  • HTTP requests to localhost/127.0.0.1 from web server process

Network Indicators:

  • Unusual outbound HTTP traffic from web server to non-standard ports
  • Requests to internal IP addresses from external-facing web server

SIEM Query:

source="web_server_logs" AND uri="/wp-admin/admin-ajax.php" AND post_data CONTAINS "action=mxchat_handle_chat_request" AND (post_data CONTAINS "localhost" OR post_data CONTAINS "127.0.0.1" OR post_data CONTAINS "192.168." OR post_data CONTAINS "10.")
