⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, privilege escalation, and remote code execution on the underlying server.
Likely Case
Unauthorized access to sensitive patient/medical data, financial data manipulation, and potential system disruption.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permissions restricting damage to specific tables.
🎯 Exploit Status

✅ Official Fix
Patch Version: Not available
Vendor Advisory: http://openhis.com
Restart Required: No
Instructions:
1. Check vendor website for patches or updates. 2. If no patch, implement workarounds immediately. 3. Consider migrating to a supported version if available.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd strict input validation and sanitization to the refund function parameters.
Modify PayController.class.php to validate and sanitize all user inputs before SQL queries
Parameterized Queries
allReplace dynamic SQL queries with parameterized/prepared statements.
Update SQL queries in refund function to use prepared statements with bound parameters
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SQL injection patterns
- Restrict network access to the OpenHIS application to trusted users only
🔍 How to Verify
Check if Vulnerable:
Review PayController.class.php for dynamic SQL queries in refund function without parameterization.Check Version:
Check OpenHIS version in configuration files or admin panel.Verify Fix Applied:
Test refund function with SQL injection payloads to ensure they are blocked or sanitized.📡 Detection & Monitoring
