🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If no patch available, implement workarounds immediately. 3. Consider migrating to alternative software if vendor is unresponsive.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries or proper input validation to /pages/settings_update.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('UPDATE settings SET value = ? WHERE id = ?'); $stmt->bind_param('si', $value, $id);
Web Application Firewall (WAF) Rules
allBlock SQL injection patterns targeting the settings_update.php endpoint
Add WAF rule: deny requests to /pages/settings_update.php with SQL keywords in ID parameter
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules (allow only trusted IPs)
- Implement database user with minimal permissions (read-only where possible)
🔍 How to Verify
Check if Vulnerable:
Test the /pages/settings_update.php endpoint with SQL injection payloads in the ID parameter (e.g., ID=1' OR '1'='1)Check Version:
Check application version in admin panel or readme filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests to /pages/settings_update.php with suspicious parameters
Network Indicators:
- HTTP POST/GET requests to /pages/settings_update.php containing SQL keywords (UNION, SELECT, etc.)
SIEM Query:
source="web_logs" AND uri="/pages/settings_update.php" AND (param="*UNION*" OR param="*SELECT*" OR param="*OR '1'='1*")
