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 · unedited
An information exposure vulnerability in FortiOS 6.2.3, 6.2.0 and below may allow an unauthenticated attacker to gain platform information such as version, models, via parsing a JavaScript file through admin webUI.

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 confidence

An information exposure vulnerability in FortiOS allows unauthenticated attackers to obtain platform version and model information by parsing JavaScript files through the administrative web interface. This info leak could aid reconnaissance for follow-up attacks.

MitigationUpgrade FortiOS to a version higher than 6.2.3. If immediate patching is not feasible, restrict administrative webUI access to trusted networks via firewall rules or disable HTTP/HTTPS management on external-facing interfaces.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify FortiOS version
    Run 'get system status' on the FortiGate CLI or check the FortiOS dashboard in the web UI. The output displays the firmware version.
    Affected if The installed version is 6.2.0 or lower.
  2. Confirm HTTP/HTTPS management is enabled
    Run 'show system interface' and look for 'set http' or 'set https' under the interface configuration, or check via web UI under Network > Interfaces.
    Affected if HTTP or HTTPS management is enabled on any interface.
  3. Determine management interface exposure
    Review the interface binding in 'show system interface' and check which IP addresses or subnets can reach the management ports. Use 'diagnostic ip address list' to see active interfaces and their addressing.
    Affected if The management interface (HTTP/HTTPS) is bound to an interface accessible from untrusted networks (such as WAN, dial-up, or any interface with 0.0.0.0/0 reachability from outside).

A system is affected if it runs FortiOS version 6.2.0 or lower AND has the administrative web interface (HTTP/HTTPS) enabled and accessible from untrusted networks.

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 data
Upgrade available Upgrade to a release after 6.2.0
Interim mitigation

Upgrade FortiOS to a version higher than 6.2.3. If immediate patching is not feasible, restrict administrative webUI access to trusted networks via firewall rules or disable HTTP/HTTPS management on external-facing interfaces.
