Detection & IOCs extracted from sources · hover to see the quote

• → Detect brute force authentication attempts against FortiClientEMS console via HTTP or HTTPS — monitor for excessive failed login requests from a single source IP targeting the EMS login endpoint ↗
• → Alert on high volumes of unauthenticated HTTP/HTTPS authentication requests to FortiClientEMS (versions 7.2.0–7.2.4 or before 7.0.10) — no account lockout or rate-limiting is enforced, making rapid sequential login attempts a reliable signal ↗

• · Affected versions are FortiClientEMS 7.2.0 through 7.2.4 and all versions before 7.0.10 — detections and mitigations should be scoped to these version ranges ↗
• · The vulnerability is exploitable by unauthenticated attackers, meaning no prior credential or session is required — network-level access to the EMS console (HTTP/HTTPS) is the only prerequisite ↗
