🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Update to a patched version if available from the vendor
2. If no official patch, implement parameterized queries and input validation
3. Review and sanitize all user inputs in the application
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests
Input Validation Filter
allImplement server-side validation to restrict invoice_number to expected formats
🧯 If You Can't Patch
- Implement network segmentation to isolate the Pharmacy Management System from other critical systems
- Enable detailed logging and monitoring of all database queries and access attempts
🔍 How to Verify
Check if Vulnerable:
Test the sales_report.php endpoint with SQL injection payloads in the invoice_number parameter (e.g., invoice_number=1' OR '1'='1)Check Version:
Check git commit hash: git log --oneline -1Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages or are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts or parameter manipulation in web server logs
- Unexpected database schema changes or data extraction patterns
Network Indicators:
- SQL keywords in HTTP GET/POST parameters (SELECT, UNION, INSERT, etc.)
- Unusual database connection patterns from web servers
SIEM Query:
