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 exposure of sensitive information to an unauthorized actor [CWE-200] vulnerability in Fortinet FortiFone 7.0.0 through 7.0.1, FortiFone 3.0.13 through 3.0.23 allows an unauthenticated attacker to obtain the device configuration via crafted HTTP or HTTPS requests.

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 · moderate confidence

An unauthenticated attacker can obtain the full device configuration of FortiFone 7.0.0-7.0.1 and 3.0.13-3.0.23 devices by sending crafted HTTP/HTTPS requests. The configuration likely contains sensitive information including credentials, network settings, and system parameters, exposing the device to further compromise.

MitigationApply vendor-supplied firmware patches to upgrade vulnerable FortiFone devices to fixed versions. Until patched, restrict external access to HTTP/HTTPS management interfaces using firewall rules or VPNs.

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 FortiFone devices on the network
    Scan the network for devices responding on HTTP (port 80) and HTTPS (port 443) that present FortiFone web management interfaces. Note the IP addresses of discovered FortiFone units.
    Affected if Any FortiFone device matching versions 7.0.0-7.0.1 or 3.0.13-3.0.23 is present on the network
  2. Determine the installed FortiFone firmware version
    Access the FortiFone admin interface via HTTPS and navigate to System > Firmware or About section to view the running firmware version. Alternatively, check the device directly or review asset inventory records.
    Affected if The firmware version is 7.0.0 through 7.0.1 or 3.0.13 through 3.0.23 (inclusive)
  3. Verify management interface network exposure
    Determine whether the FortiFone HTTP/HTTPS management ports are accessible from network segments that contain untrusted or external users (e.g., the internet, guest networks). Use port scanning from an external perspective or review firewall rules governing access to the device.
    Affected if The management interface is reachable from untrusted networks without authentication barriers
  4. Review access logs for unauthenticated configuration requests
    Examine FortiFone access logs, web server logs, or upstream firewall logs for HTTP/HTTPS requests to configuration endpoints that occurred without prior authentication. Look for requests to paths that return device configuration data.
    Affected if Logs show configuration retrieval requests from unauthenticated or unexpected IP addresses

A user is affected if they have any FortiFone device running firmware version 7.0.0-7.0.1 or 3.0.13-3.0.23 with its management interface exposed to the network, as the vulnerability allows unauthenticated configuration disclosure.
