CVE-2024-6584

9.1 CRITICAL

📋 TL;DR

This vulnerability in WordPress allows administrators to make arbitrary GET requests to any URL through the 'wp_ajax_boost_proxy_ig' action. It enables server-side request forgery (SSRF) attacks, potentially exposing internal services or performing unauthorized actions. All WordPress sites with the vulnerable component are affected.

💻 Affected Systems

Products:
  • WordPress
Versions: Specific plugin/component versions not specified in reference
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: Requires the vulnerable component/plugin to be installed and activated. Administrator access is needed to exploit.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could use the vulnerable endpoint to access internal services, exfiltrate sensitive data, or chain with other vulnerabilities to achieve remote code execution.

🟠

Likely Case

Attackers would use this to scan internal networks, access metadata services (like AWS/Azure instance metadata), or interact with internal APIs that shouldn't be exposed.

🟢

If Mitigated

With proper network segmentation and firewall rules, the impact would be limited to accessing only allowed external resources.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploitation requires administrator-level access. The vulnerability is publicly documented with proof-of-concept available.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check plugin/component vendor for specific version

Vendor Advisory: https://wpscan.com/vulnerability/eaa57c8c-1cac-4903-9763-79f7f84469fa/

Restart Required: No

Instructions:

1. Identify the vulnerable WordPress plugin/component. 2. Update to the latest patched version from the official repository. 3. Verify the update was successful by checking the version.

🔧 Temporary Workarounds

Disable vulnerable endpoint

all

Remove or disable the 'wp_ajax_boost_proxy_ig' action handler

Edit WordPress theme/plugin files to remove add_action('wp_ajax_boost_proxy_ig', ...) calls

Restrict administrator access

all

Limit administrator accounts to only trusted users and implement strong authentication

🧯 If You Can't Patch

  • Implement network segmentation to isolate WordPress from internal services
  • Deploy web application firewall (WAF) rules to block SSRF patterns

🔍 How to Verify

Check if Vulnerable:

Check if the 'wp_ajax_boost_proxy_ig' action exists in your WordPress installation by reviewing plugin/theme code

Check Version:

Check WordPress admin dashboard or use wp-cli: wp plugin list --field=version

Verify Fix Applied:

After updating, test that the vulnerable endpoint no longer accepts arbitrary URLs

📡 Detection & Monitoring

Log Indicators:

  • Unusual GET requests from WordPress to internal IPs
  • Requests to metadata services (169.254.169.254, 169.254.170.2)
  • Multiple rapid requests to different internal endpoints

Network Indicators:

  • WordPress server making unexpected outbound connections to internal networks
  • Traffic patterns suggesting internal network scanning

SIEM Query:

source="wordpress" AND (url="*wp-admin/admin-ajax.php*" AND action="boost_proxy_ig")
