CVE-2025-60574
📋 TL;DR
A Local File Inclusion vulnerability in tQuadra CMS 4.2.1117 allows attackers to read arbitrary files from the server by exploiting improper input sanitization in the /styles/ path. This affects all systems running the vulnerable version of tQuadra CMS. Attackers can retrieve sensitive files like configuration files, passwords, or source code.
💻 Affected Systems
- tQuadra CMS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through retrieval of sensitive configuration files, database credentials, or SSH keys leading to lateral movement and data exfiltration.
Likely Case
Information disclosure of sensitive files including configuration files, logs, and potentially user data stored on the server.
If Mitigated
Limited impact with proper file permissions and web server configuration restricting access to sensitive directories.
🎯 Exploit Status
Exploitation requires only a crafted GET request to the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
1. Monitor vendor channels for security updates. 2. Apply patch when available. 3. Test in development environment before production deployment.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to block directory traversal attempts in the /styles/ path.
# Add input validation in the affected PHP file
# Example: if (strpos($input, '../') !== false) { die('Invalid input'); }
Web Server Restriction
allConfigure web server to restrict access to sensitive directories and block traversal patterns.
# Apache .htaccess example
RewriteCond %{REQUEST_URI} \.\. [NC]
RewriteRule .* - [F]
# Nginx configuration example
location ~* \.\. { deny all; }
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) rules to block LFI patterns and directory traversal attempts.
- Restrict file system permissions to limit what files the web server user can access.
🔍 How to Verify
Check if Vulnerable:
Test by sending a crafted GET request to /styles/ endpoint with directory traversal payload (e.g., ../../../etc/passwd) and check if sensitive file contents are returned.Check Version:
Check tQuadra CMS version in admin panel or configuration files.Verify Fix Applied:
After applying workarounds, test the same payloads to confirm they are blocked or return error messages instead of file contents.📡 Detection & Monitoring
Log Indicators:
- HTTP GET requests to /styles/ containing ../ patterns
- Unusual file access patterns from web server process
Network Indicators:
- HTTP requests with directory traversal sequences in URL parameters
SIEM Query:
source="web_server_logs" AND url="*/styles/*" AND (url="*../*" OR url="*..\\*" OR url="*%2e%2e%2f*")
