🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If no patch available, implement workarounds. 3. Consider replacing with alternative software if unmaintained.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize difficulty_id parameter before processing
Modify btn_functions.php to validate difficulty_id as integer using is_numeric() or filter_var()
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Add WAF rule: deny requests containing SQL keywords in difficulty_id parameter
🧯 If You Can't Patch
- Restrict access to /system/system/admins/assessments/pretest/ directory via .htaccess or firewall rules
- Implement network segmentation to isolate the vulnerable system from sensitive databases
🔍 How to Verify
Check if Vulnerable:
Test by sending SQL injection payloads to the difficulty_id parameter in btn_functions.php requestsCheck Version:
Check system version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return appropriate error messages📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed parameter validation attempts
- Requests with SQL keywords in difficulty_id parameter
Network Indicators:
- HTTP requests containing SQL injection patterns
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND (uri="*btn_functions.php*" AND (param="*difficulty_id*SELECT*" OR param="*difficulty_id*UNION*" OR param="*difficulty_id*OR*"))
