🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider implementing workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries and input validation to customer_update.php
Modify /pages/customer_update.php to use prepared statements with parameterized queries instead of direct string concatenation
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Configure WAF to block requests containing SQL keywords and special characters in the ID parameter
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules to only trusted IP addresses
- Implement database user with minimal permissions (read-only if possible) for the application
🔍 How to Verify
Check if Vulnerable:
Check if /pages/customer_update.php exists and accepts ID parameter. Test with SQL injection payloads like ' OR '1'='1Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Test with SQL injection payloads after implementing fixes. Verify no database errors or unexpected behavior occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web server
- SQL syntax errors in application logs
- Multiple failed parameter validation attempts
Network Indicators:
- HTTP requests to /pages/customer_update.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
