🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-janobe-products
Restart Required: No
Instructions:
1. Check vendor for updated version. 2. If no patch available, implement workarounds immediately. 3. Monitor vendor communications for security updates.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation for the 'studid' parameter to only accept expected data types and formats.
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint.
🧯 If You Can't Patch
- Disable the vulnerable payment module immediately and use alternative payment methods.
- Implement network segmentation to isolate the vulnerable system from sensitive data stores.
🔍 How to Verify
Check if Vulnerable:
Check if version 1.0 of the payment module is installed and if '/candidate/controller.php' accepts 'studid' parameter without proper validation.
Check Version:
Check application configuration files or admin panel for module version information.
Verify Fix Applied:
Test the vulnerable endpoint with SQL injection payloads to ensure they are properly rejected or sanitized.
📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple rapid requests to '/candidate/controller.php' with varying 'studid' parameters
- Database queries with unexpected syntax or structure
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in the 'studid' parameter
- Unusual traffic patterns to the vulnerable endpoint
SIEM Query:
source="web_logs" AND uri="/candidate/controller.php" AND (query="*SELECT*" OR query="*UNION*" OR query="*OR*1=1*")
