🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If no patch available, implement workarounds. 3. Consider migrating to alternative software.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the employeeid parameter before processing
Modify /check_availability.php to validate employeeid as numeric only
Web Application Firewall Rule
allBlock SQL injection patterns targeting the employeeid parameter
Add WAF rule: deny requests with SQL keywords in employeeid parameter
🧯 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 queries from the application
🔍 How to Verify
Check if Vulnerable:
Test /check_availability.php with SQL injection payloads in employeeid parameter (e.g., employeeid=1' OR '1'='1)
Check Version:
Check software version in admin panel or readme files
Verify Fix Applied:
Test with same payloads after implementing fixes - should return error or no data instead of executing SQL
