CVE-2014-2216
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe FortiManager protocol service in Fortinet FortiOS before 4.3.16 and 5.0.0 before 5.0.8 on FortiGate devices allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted request.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA vulnerability in the FortiManager protocol service in FortiOS allows remote attackers to send crafted requests that can cause denial of service and potentially execute arbitrary code on affected FortiGate devices running FortiOS versions prior to 4.3.16 or 5.0.8.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify FortiOS versionRun the command 'get system status' or 'fnsysctl get system status' on the FortiGate CLI to retrieve the firmware versionAffected if The displayed FortiOS version is 4.3.15 or earlier, or any of these: 4.3.10, 4.3.12, 4.3.13, 4.3.14, 5.0.0, 5.0.3, 5.0.4, 5.0.5, 5.0.6, or 5.0.7
-
Confirm FortiManager protocol service is enabledRun 'get system fm' or 'show system central-management' in FortiGate CLI to check if FortiManager management is configuredAffected if The FortiManager or central management service is enabled and the device is manageable by FortiManager
-
Check FortiManager listener statusRun 'diagnose system service list' or check 'diagnose debug application fortimanager' to see if the FortiManager protocol service is listening on ports 541/542Affected if The FortiManager protocol service listener is active on the device
-
Assess network exposureReview firewall policies and network access control lists to determine if port 541 or 542 (FortiManager protocol) is exposed to untrusted networksAffected if The FortiManager service port is reachable from outside the trusted management network
The device is affected if it is a FortiGate running any FortiOS version listed as vulnerable AND the FortiManager protocol service is enabled and accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade FortiOS to version 4.3.16 or later for 4.x branches, or 5.0.8 or later for 5.0.x branches. If immediate upgrading is not feasible, restrict network access to the FortiManager protocol service and implement network segmentation to reduce exposure.
