🔍 How to Verify
Check if Vulnerable:
Check router firmware version via web interface or CLI; if version is V1.1.0.54_1.0.1, it is vulnerable.Check Version:
Check router web interface under Advanced > Administration > Router Status or similar.Verify Fix Applied:
Update firmware to a newer version if available and confirm version change.📡 Detection & Monitoring
Log Indicators:
- Unusual access logs to router URLs or directories, especially from unauthorized IPs.
Network Indicators:
- HTTP requests to embedded router paths from unexpected sources.
SIEM Query:
source="router_logs" AND (url_path CONTAINS "/firmware/" OR url_path CONTAINS "/config/")
