CVE-2024-6946
📋 TL;DR
This vulnerability in Flute CMS allows remote attackers to inject malicious code through the /admin/pages/list endpoint by manipulating the 'blocks' parameter. This affects all systems running Flute CMS 0.2.2.4-alpha with the vulnerable admin interface exposed. Attackers can execute arbitrary code on the server if successful.
💻 Affected Systems
- Flute CMS
📦 What is this software?
Flute by Flute Cms
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within the network.
Likely Case
Unauthorized code execution allowing website defacement, data manipulation, or installation of backdoors.
If Mitigated
Limited impact with proper network segmentation and admin interface restrictions.
🎯 Exploit Status
Exploit requires authentication to the admin interface. Public proof-of-concept code is available in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Restrict Admin Access
allBlock external access to /admin/ paths using firewall rules or web server configuration
# Apache: RewriteRule ^/admin/ - [F,L]
# Nginx: location /admin/ { deny all; }
Input Validation
allAdd server-side validation for the 'blocks' parameter in /admin/pages/list
# Implement proper input sanitization in the affected PHP file
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the Flute CMS instance
- Enable detailed logging and monitoring for suspicious activity on /admin/pages/list
🔍 How to Verify
Check if Vulnerable:
Check if running Flute CMS version 0.2.2.4-alpha and if /admin/pages/list endpoint is accessibleCheck Version:
Check Flute CMS configuration files or admin panel for version informationVerify Fix Applied:
Test if code injection is possible through the 'blocks' parameter after implementing workarounds📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /admin/pages/list with suspicious 'blocks' parameter values
- PHP execution errors or unexpected code execution logs
Network Indicators:
- HTTP requests to /admin/pages/list with encoded or suspicious payloads in parameters
