🛠️ 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. Implement workarounds immediately.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize the ID parameter in transaction_del.php to accept only numeric values.
Modify /pages/transaction_del.php to include: if(!is_numeric($_GET['ID'])) { die('Invalid input'); }
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection rules to block malicious requests to /pages/transaction_del.php.
🧯 If You Can't Patch
- Restrict network access to the system using firewall rules to allow only trusted IP addresses.
- Implement database user permissions with least privilege, ensuring the application database user cannot execute dangerous commands.
🔍 How to Verify
Check if Vulnerable:
Test by sending a crafted request to /pages/transaction_del.php?ID=1' OR '1'='1 and checking for SQL errors or unexpected behavior.Check Version:
Check the system version in the admin panel or by reviewing the software documentation/installation files.Verify Fix Applied:
After applying workarounds, retest with the same payload; it should return an error message or no data instead of executing SQL.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple requests to /pages/transaction_del.php with suspicious ID parameters
Network Indicators:
- HTTP requests containing SQL keywords (e.g., UNION, SELECT, OR) in the ID parameter
SIEM Query:
source="web_logs" AND uri="/pages/transaction_del.php" AND (query="*OR*" OR query="*UNION*" OR query="*SELECT*")
