📋 TL;DR
Hospital Management System v1.0 contains a SQL injection vulnerability in the delid parameter at viewtreatmentrecord.php that allows attackers to execute arbitrary SQL commands. This affects all deployments of this specific software version. Attackers could potentially access, modify, or delete sensitive medical data.
💻 Affected Systems
- Hospital Management System
📦 What is this software?
Hospital Management System by Hospital Management System Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to exposure of all patient records, medical history, treatment data, and potential authentication bypass to administrative functions.
Likely Case
Data exfiltration of patient records and treatment information, potentially leading to medical identity theft or privacy violations.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, restricting SQL injection attempts.
🎯 Exploit Status
SQL injection via GET parameter is trivial to exploit with automated tools. Public proof-of-concept available in GitHub repository.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
No official patch available. Implement parameterized queries and input validation in viewtreatmentrecord.php.
🔧 Temporary Workarounds
Web Application Firewall
allDeploy WAF with SQL injection rules to block malicious requests
Input Validation
allAdd server-side validation to ensure delid parameter contains only expected values
🧯 If You Can't Patch
- Isolate the Hospital Management System behind a reverse proxy with strict input filtering
- Implement network segmentation to restrict access to the database server
🔍 How to Verify
Check if Vulnerable:
Test viewtreatmentrecord.php with SQL injection payloads in delid parameter (e.g., ' OR '1'='1)Check Version:
Check software version in application interface or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return appropriate error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed parameter validation attempts
Network Indicators:
- HTTP requests to viewtreatmentrecord.php with SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri="*viewtreatmentrecord.php*" AND (param="*SELECT*" OR param="*UNION*" OR param="*OR*" OR param="*--*")
