Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If patch available, download and apply. 3. Test functionality after patching. 4. Monitor for any issues.
🔧 Temporary Workarounds
Input Validation Filter

- Implement database user with minimal privileges (read-only if possible) for the web application.
🔍 How to Verify
Check if Vulnerable:
Test the discount parameter with SQL injection payloads like ' OR '1'='1 and observe database errors or unexpected behavior.Check Version:
Check system documentation or admin interface for version information; typically shows 'Version 1.0' in footer or about page.Verify Fix Applied:
Retest with SQL injection payloads after applying fixes; should return proper error messages or reject input without database interaction.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /pages/sales_add.php with SQL keywords in parameters
- Database error logs showing SQL syntax errors from web application
Network Indicators:
- Unusual database queries originating from web server IP
- Multiple rapid requests to sales_add.php with varying parameters
SIEM Query:
source="web_logs" AND uri="/pages/sales_add.php" AND (param="discount" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|or|and|--|#)")
