Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Consider replacing with alternative software.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF with SQL injection rules to block malicious requests to /view_bill.php
Input Validation Filter
allAdd input validation to sanitize the 'id' parameter before processing
Modify /view_bill.php to validate id parameter as integer
🧯 If You Can't Patch
- Isolate the system on a segmented network with strict access controls
- Implement database-level protections: use least privilege accounts, enable audit logging
🔍 How to Verify
Check if Vulnerable:
Test /view_bill.php?id=1' OR '1'='1 to see if SQL error occurs
Check Version:
Check application version in admin panel or configuration files
Verify Fix Applied:
Test with same payload; should return error page or sanitized response without SQL errors
📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in application logs
- Unusual database queries from web server
- Multiple failed parameter attempts on /view_bill.php
Network Indicators:
- HTTP requests to /view_bill.php with SQL injection payloads
