💻 Affected Systems
- Hospital Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to theft of all patient records, administrative credentials, and potential remote code execution on the database server.
Likely Case
Unauthorized access to patient data, modification of medical records, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
Multiple public exploit scripts and detailed analysis available; exploitation requires minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
1. Manually patch the vulnerable func.php file by implementing parameterized queries or input validation. 2. Replace raw SQL queries with prepared statements. 3. Sanitize all user inputs, especially the email parameter.
🔧 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 reject suspicious email parameter values containing SQL keywords.
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only.
- Implement strict network segmentation and monitor all database access attempts.
🔍 How to Verify
Check if Vulnerable:
Test the /Hospital-Management-System-master/func.php endpoint with SQL injection payloads in the email parameter.Check Version:
Check the software version in the application interface or configuration files.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and that parameterized queries are implemented.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts with SQL payloads
- Unexpected database queries from web server IP
Network Indicators:
- HTTP requests to func.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/func.php" AND (email="*' OR *" OR email="*;*" OR email="*--*" OR email="*UNION*" OR email="*SELECT*" OR email="*INSERT*" OR email="*UPDATE*" OR email="*DELETE*")🔗 References
