🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch exists. Replace vulnerable code with parameterized queries or prepared statements in createClassArms.php.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for classId and classArmName parameters.
Web Application Firewall (WAF)
allDeploy a WAF to block SQL injection attempts targeting the vulnerable endpoint.
🧯 If You Can't Patch
- Restrict network access to the system to trusted users only.
- Monitor logs for suspicious SQL queries or unauthorized access attempts.
🔍 How to Verify
Check if Vulnerable:
Test the createClassArms.php endpoint with SQL injection payloads in classId or classArmName parameters.Check Version:
Check the software version in the system's admin panel or configuration files.Verify Fix Applied:
Verify that parameterized queries are implemented and SQL injection attempts no longer succeed.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts or parameter tampering
Network Indicators:
- HTTP requests to createClassArms.php with SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri="*createClassArms.php*" AND (param="*classId*" OR param="*classArmName*") AND (query="*SELECT*" OR query="*UNION*" OR query="*OR 1=1*")
