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 password recovery process vulnerability in Fortinet FortiPortal versions 4.0.0 and below allows an attacker to execute unauthorized code or commands via a hidden Close button

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

FortiPortal versions 4.0.0 and below contain a weak password recovery process where a hidden Close button can be manipulated to achieve remote code execution, allowing attackers to execute unauthorized commands on the affected system.

MitigationUpgrade FortiPortal to a version above 4.0.0. If immediate patching is not possible, restrict network access to the password recovery interface and monitor for suspicious authentication 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 if FortiPortal is installed
    Check for FortiPortal processes running on the system or look for FortiPortal installation directories and services
    Affected if FortiPortal software is found running on the system
  2. Determine the FortiPortal version
    Access the FortiPortal web interface or check version files in the installation directory to identify the exact version number
    Affected if The installed version is 4.0.0 or below
  3. Verify password recovery interface accessibility
    Check network accessibility of the FortiPortal password recovery endpoint (typically port 443 or 8080) from external networks
    Affected if The password recovery interface is exposed to untrusted networks
  4. Look for signs of unauthorized command execution
    Review system logs, process logs, and network logs for unexpected commands or scripts originating from the FortiPortal service
    Affected if Suspicious commands or unexpected shell executions are found in logs associated with FortiPortal

You are affected if FortiPortal version 4.0.0 or below is installed and its password recovery interface is network-accessible.
