🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the Username parameter in /process.php
Modify /process.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ?'); $stmt->bind_param('s', $username);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting /process.php
Add WAF rule: Block requests to /process.php containing SQL keywords in Username parameter
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the web server
🔍 How to Verify
Check if Vulnerable:
Test /process.php with SQL injection payloads in Username parameter (e.g., admin' OR '1'='1)Check Version:
Check system documentation or admin panel for version informationVerify Fix Applied:
Test with same payloads after implementing parameterized queries - should return error or no data📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts with SQL syntax in Username field
- Unusual database queries from web server IP
Network Indicators:
- HTTP POST requests to /process.php containing SQL keywords
- Abnormal response sizes from authentication endpoints
SIEM Query:
source="web_logs" AND uri="/process.php" AND (username CONTAINS "'" OR username CONTAINS "OR" OR username CONTAINS "--")
