⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of patient database including theft of all medical records, deletion of critical patient data, or installation of backdoors for persistent access.
Likely Case
Unauthorized access to patient records, potential data exfiltration, and manipulation of room type data affecting hospital operations.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification.

🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Implement workarounds immediately.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify manage_room_type.php to use prepared statements and validate the 'id' parameter
Replace direct SQL queries with PDO or mysqli prepared statements in the PHP code
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Add WAF rule: SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement database-level protections: restrict application database user permissions to minimum required
🔍 How to Verify
Check if Vulnerable:
Test the URL hprms/admin/room_types/manage_room_type.php?id=1' with SQL injection payloads like ' OR '1'='1Check Version:
Check system version in admin panel or configuration filesVerify Fix Applied:
Test with same payloads after implementing fixes - should return error pages or no data leakage📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple failed login attempts followed by SQL injection patterns
- Requests with SQL keywords in 'id' parameter
Network Indicators:
- Unusual database query patterns from web server
- Large data transfers from database to external IPs
SIEM Query:
source="web_logs" AND ("SQL syntax" OR "mysql_fetch" OR "You have an error in your SQL syntax")
