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
Multiple uncontrolled resource consumption vulnerabilities in the web interface of FortiPortal before 6.0.6 may allow a single low-privileged user to induce a denial of service via multiple HTTP 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

FortiPortal versions before 6.0.6 contain uncontrolled resource consumption vulnerabilities in the web interface. A single low-privileged authenticated user can send multiple HTTP requests that exhaust server resources, leading to denial of service for other users.

MitigationUpgrade FortiPortal to version 6.0.6 or later to obtain the patch for these resource consumption vulnerabilities.

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. Confirm FortiPortal is installed
    Check for FortiPortal processes or services running on the system. On Linux, run 'ps aux | grep -i fortiportal' or check for /opt/fortiportal directory. On Windows, check Services for FortiPortal entries.
    Affected if FortiPortal is not found on the system, then not affected.
  2. Identify the installed FortiPortal version
    Log into the FortiPortal admin interface and navigate to System > Settings > About, or check the version file if accessible via CLI. Alternatively, check the version string in the installation directory or RPM/DEB package.
    Affected if The version cannot be determined, treat as potentially affected.
  3. Compare version against affected ranges
    Evaluate the installed version against these ranges: 4.0.0 <= version < 5.3.7 OR 6.0.0 <= version < 6.0.6. If the version falls within either range, the system is affected.
    Affected if Version falls within 4.0.0 to 5.3.6, or 6.0.0 to 6.0.5.
  4. Verify web interface is enabled
    Check the FortiPortal configuration for web interface (HTTP/HTTPS) listener status. This is typically configured in the FortiPortal admin panel under System > Network > Interfaces, or check conf/system*.xml files in the installation directory.
    Affected if The web interface is enabled and the version is in the affected range, then the vulnerability is present and exploitable.

The environment is affected if FortiPortal is installed with a version between 4.0.0 and 5.3.6, or between 6.0.0 and 6.0.5, and the web interface is enabled.
