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
A weak authentication in Fortinet FortiOS versions 7.4.0 through 7.4.4, 7.2.0 through 7.2.8, 7.0.0 through 7.0.15, 6.4.0 through 6.4.15, FortiProxy versions 7.4.0 through 7.4.4, 7.2.0 through 7.2.10, 7.0.0 through 7.0.17, 2.0.0 through 2.0.14, FortiManager versions 7.6.0 through 7.6.1, 7.4.1 through 7.4.3, FortiManager Cloud versions 7.4.1 through 7.4.3, FortiAnalyzer Cloud versions 7.4.1 through 7.4.3 allows attacker to execute unauthorized code or commands via a brute-force attack.

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

This is a weak authentication vulnerability in Fortinet FortiOS, FortiProxy, FortiManager, FortiManager Cloud, and FortiAnalyzer Cloud. The flaw allows unauthenticated remote attackers to execute unauthorized code or commands via brute-force attacks against the authentication mechanism, achieving code execution without valid credentials.

MitigationApply vendor-supplied patches for all affected versions. Additionally, implement account lockout policies, enforce strong password policies, enable multi-factor authentication, and restrict management interface access to trusted networks to mitigate brute-force attempts.

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 the Fortinet product and version
    Run 'get system status' or 'get system info' on the Fortinet device CLI to determine the exact product name (FortiOS, FortiProxy, FortiManager, FortiAnalyzer) and firmware version installed.
    Affected if The product is one of FortiOS, FortiProxy, FortiManager, FortiAnalyzer, or their Cloud variants, and the version falls within: FortiOS >=6.4.0,<7.0.16 or >=7.2.0,<7.2.9 or >=7.4.0,<7.4.5; FortiProxy >=2.0.0,<2.0.15 or >=7.0.0,<7.0.18 or >=7.2.0,<7.2.11 or >=7.4.0,<7.4.5; FortiManager >=7.4.1,<7.4.4
  2. Confirm the device management interface is reachable
    Verify if the device's GUI or CLI management ports (HTTP/HTTPS on ports 443/80, or SSH on port 22) are accessible from network segments that are not fully trusted, such as the internet or DMZ networks.
    Affected if The management interface (GUI/HTTPS, HTTP, or SSH) is exposed to untrusted networks, enabling external attackers to attempt brute-force authentication.
  3. Check authentication log for brute-force attempts
    Review authentication logs via 'execute log filter category event' followed by 'execute log display' or check System Events > Authentication logs in the GUI for failed login attempts from unfamiliar IP addresses.
    Affected if There are numerous failed authentication attempts from external or untrusted IP addresses, indicating active brute-force exploitation attempts.

You are affected if you are running any of the listed Fortinet products within the specified version ranges AND the management interface is accessible from networks where untrusted or unknown users can attempt authentication.

Upgrade available Upgrade to 2.0.15 / 7.0.16 / 7.0.18 or later
Fixed in 2.0.157.0.167.0.18
Interim mitigation

Apply vendor-supplied patches for all affected versions. Additionally, implement account lockout policies, enforce strong password policies, enable multi-factor authentication, and restrict management interface access to trusted networks to mitigate brute-force attempts.

Recommended fix High confidence

FortiOS 7.4.5+ / 7.2.9+ / 7.0.16+ / 6.4.16+; FortiProxy 7.4.5+ / 7.2.11+ / 7.0.18+ / 2.0.15+; FortiManager 7.4.4+ / 7.6.2+; FortiManager Cloud 7.4.4+; FortiAnalyzer 7.4.4+ / 7.6.2+; FortiAnalyzer Cloud 7.4.4+

  1. 1. Identify the Fortinet product (FortiOS, FortiProxy, FortiManager, FortiAnalyzer, or their Cloud variants) currently deployed
  2. 2. Determine the current installed version using 'get system status' or through the web UI under System > Firmware
  3. 3. For FortiOS: upgrade to version 7.4.5 or later, or 7.2.9 or later, or 7.0.16 or later depending on your branch
  4. 4. For FortiProxy: upgrade to version 2.0.15 or later, or 7.0.18 or later, or 7.2.11 or later, or 7.4.5 or later depending on your branch
  5. 5. For FortiManager: upgrade to version 7.4.4 or later, or 7.6.2 or later depending on your branch
  6. 6. For FortiManager Cloud: upgrade to version 7.4.4 or later
  7. 7. For FortiAnalyzer: upgrade to version 7.4.4 or later, or 7.6.2 or later depending on your branch
  8. 8. For FortiAnalyzer Cloud: upgrade to version 7.4.4 or later
