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
Unauthenticated buffer overflow vulnerabilities exist within the Aruba InstantOS and ArubaOS 10 web management interface. Successful exploitation results in the execution of arbitrary commands on the underlying operating system of Aruba InstantOS 6.4.x: 6.4.4.8-4.2.4.20 and below; Aruba InstantOS 6.5.x: 6.5.4.23 and below; Aruba InstantOS 8.6.x: 8.6.0.18 and below; Aruba InstantOS 8.7.x: 8.7.1.9 and below; Aruba InstantOS 8.10.x: 8.10.0.1 and below; ArubaOS 10.3.x: 10.3.1.0 and below; Aruba has released upgrades for Aruba InnstantOS that address these security vulnerabilities.

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.

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 Aruba product running
    Access the device CLI and run 'show version' or check the web management interface login page for version information
    Affected if The device is running ArubaOS or Aruba InstantOS
  2. Determine the exact ArubaOS version
    Run 'show version' on the CLI or check the web UI. Compare your installed version against the affected range: >= 10.3.0.0 and < 10.3.1.1
    Affected if The installed version is 10.3.0.0 through 10.3.1.0
  3. Determine the exact Aruba InstantOS version
    Run 'show version' on the CLI or check the web UI. Compare against all affected ranges: 6.4.0.0 through 6.4.4.8-4.2.4.20, 6.5.0.0 through 6.5.4.23, 8.6.0.0 through 8.6.0.18, 8.7.0.0 through 8.7.1.9, or 8.10.0.0 through 8.10.0.1
    Affected if The installed version falls within any of the listed Aruba InstantOS vulnerable ranges
  4. Check for Siemens Scalance W1750d firmware
    Access the device web interface or CLI and retrieve the firmware version. All versions of this device are affected by this CVE
    Affected if The device is a Siemens Scalance W1750d regardless of version
  5. Verify web management interface exposure
    Determine if the device web management interface (HTTP/HTTPS on ports 80/443 or typical management ports) is accessible from untrusted networks
    Affected if The web management interface is network-accessible to untrusted parties, enabling remote exploitation

You are affected if you are running any version of ArubaOS within 10.3.0.0-10.3.1.0, any Aruba InstantOS version within the specified vulnerable ranges, or any Siemens Scalance W1750d firmware version, and the web management interface is network-accessible.
