🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.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 txtGasBill parameter in utility_bill_setup.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM table WHERE field = ?'); $stmt->bind_param('s', $txtGasBill);
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests
Configure WAF to block SQL injection patterns in POST/GET parameters
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement network segmentation and strict access controls to limit exposure
🔍 How to Verify
Check if Vulnerable:
Test the /setting/utility_bill_setup.php endpoint with SQL injection payloads in the txtGasBill parameterCheck Version:
Check the software version in the admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and that parameterized queries are implemented📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts from single IP
- Requests to utility_bill_setup.php with SQL keywords in parameters
Network Indicators:
- HTTP POST requests to /setting/utility_bill_setup.php containing SQL injection patterns
- Unusual database connection patterns
SIEM Query:
source="web_logs" AND uri="/setting/utility_bill_setup.php" AND (param="txtGasBill" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "OR 1=1")
