CVE-2014-2216: The FortiManager protocol service in Fortinet FortiOS before 4.3.16 and 5.0.0 before 5.0.8 on FortiGate dev...

Security readout for executives and security teams

Certain older Fortinet FortiGate firewalls running FortiOS expose a FortiManager protocol service flaw. A remote attacker could send a crafted request that may crash the device and could possibly run arbitrary code. Evidence in the bundle does not show active exploitation. Exposure is likely limited to FortiGate devices running the affected FortiOS branches, especially where the FortiManager protocol service is reachable from untrusted networks. Organizations without FortiGate/FortiOS, or already on 4.3.16, 5.0.8, or later supported releases, are less likely exposed. Treat as a high-priority legacy perimeter-device risk. The business concern is firewall disruption and possible device compromise, but urgency depends on whether affected FortiOS versions remain in use and whether management services are exposed. Mitigation focus: Upgrade affected FortiOS systems to 4.3.16, 5.0.8, or later supported Fortinet guidance.; Review Fortinet advisory FG-IR-14-006 for vendor-specific upgrade and workaround direction.; Restrict FortiManager protocol service exposure to trusted management networks only..
