🔍 How to Verify
Check if Vulnerable:
Check if accessing sensitive files like configuration files or logs is possible without authentication via browser or curlCheck Version:
Check kodbox version in admin panel or look for version file in installation directoryVerify Fix Applied:
After updating, attempt to access previously vulnerable paths and confirm access is denied📡 Detection & Monitoring
Log Indicators:
- Multiple 200 OK responses to sensitive file requests
- Access to files with extensions like .conf, .inc, .sql, .log from unauthorized IPs
Network Indicators:
- HTTP requests to sensitive file paths without authentication
- Unusual file access patterns to non-public directories
SIEM Query:
source="web_server_logs" AND (status=200 AND (uri="*.conf" OR uri="*.inc" OR uri="*.sql" OR uri="*.log"))
