📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to patient data theft, system takeover, and potential ransomware deployment across hospital infrastructure.
Likely Case
Unauthorized access to sensitive medical records, manipulation of medication data, and potential data exfiltration.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to specific tables.

🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative hospital management systems or implementing custom fixes with parameterized queries.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to reject non-numeric Med_ID values
Add PHP validation: if(!is_numeric($_GET['Med_ID'])) { die('Invalid input'); }
Web Application Firewall Rules
allBlock SQL injection patterns targeting medicines_info.php
WAF rule: deny requests to /medicines_info.php containing SQL keywords in parameters
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict IP whitelisting
- Implement database-level permissions restricting user to SELECT-only operations
🔍 How to Verify
Check if Vulnerable:
Test with payload: medicines_info.php?Med_ID=1' OR '1'='1Check Version:
Check PHP files for version comments or project documentationVerify Fix Applied:
Test with same payload - should return error or no data instead of executing SQL📡 Detection & Monitoring
Log Indicators:
- Multiple failed SQL queries in database logs
- Unusual parameter values in web server logs for medicines_info.php
Network Indicators:
- HTTP requests to medicines_info.php with SQL keywords in parameters
SIEM Query:
