Check if Vulnerable:
Check FortiManager version via GUI (System > Dashboard) or CLI (get system status). Compare against affected versions list.Check Version:
get system status | grep VersionVerify Fix Applied:
Verify version is updated to patched version and check for any abnormal processes or connections.📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts
- Unexpected process execution
- Configuration changes from unknown sources
- Failed authentication followed by successful command execution
Network Indicators:
- Unusual outbound connections from FortiManager
- Traffic to suspicious IPs/domains
- Anomalous protocol usage on management ports
SIEM Query:
source="fortimanager" AND (event_type="authentication" OR event_type="command_execution") AND result="success" AND user="unknown"
