🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries manually.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize the 'tid' parameter before processing
Modify /admin/edit-teacher-detail.php to validate tid parameter as integer
Web Application Firewall Rules
allImplement WAF rules to block SQL injection patterns targeting the edit-teacher-detail endpoint
Add WAF rule: Block requests with SQL keywords in tid parameter
🧯 If You Can't Patch
- Restrict access to /admin/ directory to trusted IP addresses only
- Implement database user with minimal necessary permissions (read-only where possible)
