CVE-2024-7426

5.3 MEDIUM

📋 TL;DR

The PeepSo WordPress plugin discloses full server path information to unauthenticated attackers through error messages in the sse.php file. This vulnerability affects all WordPress sites using PeepSo plugin versions up to 6.4.6.0. While the path disclosure alone doesn't enable direct compromise, it provides reconnaissance data that can assist in exploiting other vulnerabilities.

💻 Affected Systems

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers combine path disclosure with another vulnerability (like file inclusion or directory traversal) to achieve remote code execution or sensitive data exposure.

🟠

Likely Case

Attackers gather reconnaissance information about server structure to plan targeted attacks, potentially accelerating exploitation of other vulnerabilities.

🟢

If Mitigated

Path information is exposed but cannot be leveraged due to proper security controls and absence of other vulnerabilities.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: LOW

🎯 Exploit Status

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

Exploitation requires direct access to sse.php file and triggering error conditions. No authentication required.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 6.4.6.1 or later

Vendor Advisory: https://wordpress.org/plugins/peepso-core/#developers

Restart Required: No

Instructions:

1. Log into WordPress admin panel. 2. Navigate to Plugins → Installed Plugins. 3. Find PeepSo plugin and click 'Update Now'. 4. Verify plugin version is 6.4.6.1 or higher.

🔧 Temporary Workarounds

Disable error display

all

Configure WordPress to suppress error messages from being displayed to users

Add to wp-config.php: define('WP_DEBUG', false);
Add to wp-config.php: define('WP_DEBUG_DISPLAY', false);

Restrict access to sse.php

linux

Block direct access to the vulnerable file using web server configuration

For Apache (.htaccess): <Files "sse.php"> Require all denied </Files>
For Nginx: location ~ /sse\.php$ { deny all; }

🧯 If You Can't Patch

  • Implement web application firewall (WAF) rules to block requests to sse.php file
  • Monitor access logs for unusual requests to sse.php and investigate

🔍 How to Verify

Check if Vulnerable:

Access https://yoursite.com/wp-content/plugins/peepso-core/sse.php directly and check if server path information is displayed in error messages

Check Version:

wp plugin list --name=peepso-core --field=version (WP-CLI) or check WordPress admin plugins page

Verify Fix Applied:

After updating, attempt to access sse.php file and verify no path information is disclosed

📡 Detection & Monitoring

Log Indicators:

  • HTTP requests to /wp-content/plugins/peepso-core/sse.php
  • Error logs containing full server path disclosures

Network Indicators:

  • Unusual GET requests to sse.php endpoint from external IPs

SIEM Query:

source="web_access_logs" AND uri="/wp-content/plugins/peepso-core/sse.php"
