CVE-2025-50692
📋 TL;DR
FoxCMS versions up to 1.2.5 contain a code injection vulnerability in the admin template file editor that allows authenticated attackers to execute arbitrary code on the server. This affects all FoxCMS installations with the vulnerable component enabled. Attackers with admin access can achieve remote code execution.
💻 Affected Systems
- FoxCMS
📦 What is this software?
Foxcms by Foxcms
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise leading to data theft, ransomware deployment, or use as a foothold for lateral movement within the network.
Likely Case
Authenticated attackers gaining shell access to the web server, potentially compromising the entire FoxCMS installation and underlying server.
If Mitigated
Attackers with admin credentials can still execute code but proper network segmentation and monitoring would limit lateral movement.
🎯 Exploit Status
Exploitation requires admin credentials but is straightforward once authenticated.
🛠️ 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
Disable template file editor
linuxRemove or restrict access to the vulnerable admin/template_file/editFile.html component
mv /path/to/admin/template_file/editFile.html /path/to/admin/template_file/editFile.html.disabled
Implement strict access controls
allRestrict admin panel access to specific IP addresses using web server configuration
# Apache: Require ip 192.168.1.0/24
# Nginx: allow 192.168.1.0/24; deny all;
🧯 If You Can't Patch
- Implement network segmentation to isolate FoxCMS from critical systems
- Enable detailed logging and monitoring for suspicious admin panel activity
🔍 How to Verify
Check if Vulnerable:
Check FoxCMS version in admin panel or configuration files. If version <= 1.2.5 and admin/template_file/editFile.html exists, system is vulnerable.
Check Version:
grep -r 'version' /path/to/foxcms/config/ files or check admin dashboard
Verify Fix Applied:
Verify editFile.html is removed/disabled or system is upgraded beyond v1.2.5
📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to admin/template_file/editFile.html
- Suspicious file modifications in template directories
- Unexpected system command execution from web process
Network Indicators:
- HTTP requests containing code injection patterns to the vulnerable endpoint
- Outbound connections from web server to unexpected destinations
SIEM Query:
source="web_logs" AND uri="/admin/template_file/editFile.html" AND (method="POST" OR status=200)
