📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or full system takeover via SQL injection to RCE chaining.
Likely Case
Unauthorized access to sensitive appointment data, patient information, and administrative credentials stored in the database.
If Mitigated
Limited impact if database permissions are restricted and web application firewall blocks SQL injection patterns.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub. Attack requires access to the admin interface but not necessarily authentication if admin panel is unprotected.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider applying input validation and parameterized queries to the vulnerable file.
🔧 Temporary Workarounds
Web Application Firewall
allDeploy a WAF with SQL injection rules to block malicious requests to /admin/deletedoctorclinic.php
Access Restriction
linuxRestrict access to /admin/ directory to trusted IP addresses only
# Apache:
<Location /admin/>
Require ip 192.168.1.0/24
</Location>
# Nginx:
location /admin/ {
allow 192.168.1.0/24;
deny all;
}
🧯 If You Can't Patch
- Remove or rename /admin/deletedoctorclinic.php file if functionality is not required
- Implement network segmentation to isolate the booking system from critical databases
🔍 How to Verify
Check if Vulnerable:
Check if file /admin/deletedoctorclinic.php exists and contains unsanitized 'clinic' parameter usage. Test with SQL injection payloads like ' OR '1'='1Check Version:
Check version in application files or database configuration. Look for version indicators in source code or documentation.Verify Fix Applied:
Verify that input validation is implemented and SQL queries use parameterized statements. Test with same payloads that should be rejected.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application user
- Multiple requests to /admin/deletedoctorclinic.php with SQL keywords
Network Indicators:
- HTTP requests containing SQL injection patterns targeting 'clinic' parameter
- Unusual database port traffic from web server
SIEM Query:
source="web_logs" AND uri="/admin/deletedoctorclinic.php" AND (request CONTAINS "UNION" OR request CONTAINS "SELECT" OR request CONTAINS "OR '1'='1'")
