CVE-2024-47051
📋 TL;DR
This CVE addresses two critical vulnerabilities in Mautic versions before 5.2.3: a Remote Code Execution (RCE) via asset upload that allows authenticated users to upload executable PHP files, and a Path Traversal vulnerability that enables arbitrary file deletion. Organizations running vulnerable Mautic instances with authenticated user accounts are affected.
💻 Affected Systems
- Mautic
📦 What is this software?
Mautic by Acquia
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary code, delete critical system files, and potentially gain persistent access to the entire server infrastructure.
Likely Case
Data loss, service disruption, and potential lateral movement within the network as attackers exploit authenticated access to manipulate files and execute malicious code.
If Mitigated
Limited impact if proper file upload restrictions and authentication controls are in place, though authenticated users could still cause damage.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once authentication is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.2.3
Vendor Advisory: https://github.com/mautic/mautic/security/advisories/GHSA-73gx-x7r9-77x2
Restart Required: No
Instructions:
1. Backup your Mautic instance and database. 2. Update to Mautic version 5.2.3 or later via the built-in updater or manual installation. 3. Verify the update completed successfully.
🔧 Temporary Workarounds
Restrict File Upload Extensions
allImplement strict file extension validation at the web server level to block PHP and other executable file uploads.
# For Apache: Add to .htaccess
<FilesMatch "\.(php|phtml|php3|php4|php5|php7|phps|phar)$">
Order Allow,Deny
Deny from all
</FilesMatch>
# For Nginx: Add to server block
location ~ \.(php|phtml|php3|php4|php5|php7|phps|phar)$ {
deny all;
}
Restrict User Permissions
allLimit authenticated user permissions to only essential functions and implement principle of least privilege.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Mautic instances from critical systems.
- Deploy web application firewall (WAF) rules to block suspicious file upload patterns and path traversal attempts.
🔍 How to Verify
Check if Vulnerable:
Check Mautic version in the admin dashboard or via the database: SELECT * FROM mautic_core_config WHERE bundle = 'core' AND name = 'mautic_version'Check Version:
php bin/console mautic:versionVerify Fix Applied:
Confirm version is 5.2.3 or higher in the admin dashboard or via the version check command.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads with PHP extensions
- Failed file deletion attempts with unusual paths
- Multiple authentication attempts followed by file operations
Network Indicators:
- POST requests to asset upload endpoints with executable file types
- HTTP requests containing path traversal sequences (../)
