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.

dbcve analysis · high confidence

Unauthenticated buffer overflow vulnerabilities in the Aruba InstantOS and ArubaOS 10 web management interface allow remote attackers to execute arbitrary commands on the underlying operating system. The flaws are exploitable without authentication, making them particularly dangerous.

MitigationApply vendor-supplied firmware updates to all affected Aruba InstantOS and ArubaOS devices to address the buffer overflow 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. Identify the ArubaOS version
    Access the device CLI and run 'show version' or 'show system info' to display the installed ArubaOS firmware version.
    Affected if The version is >= 10.3.0.0 and < 10.3.1.1
  2. Identify the Aruba Instant version
    Access the controller CLI and run 'show version' or check the Instant AP image version via 'show instantap image-version'.
    Affected if The version matches any of these ranges: >= 6.4.0.0 and < 6.4.4.8-4.2.4.21; >= 6.5.0.0 and < 6.5.4.24; >= 8.6.0.0 and < 8.6.0.19; >= 8.7.0.0 and < 8.7.1.10; >= 8.10.0.0 and < 8.10.0.2
  3. Verify the web management interface is accessible
    Confirm the device has the web management interface (WebUI) enabled by checking 'show web-server' or attempting to reach HTTP/HTTPS on the management IP.
    Affected if The web management interface is enabled and the device version falls within the affected ranges above; this vulnerability is exploitable through the web interface without authentication.
  4. Identify Siemens Scalance W1750d firmware version
    For Siemens Scalance W1750d devices, check the firmware version via the device web interface or CLI using 'show version' or similar command.
    Affected if Any version of Siemens Scalance W1750d firmware is installed, as all versions are affected.

The device is affected if it runs ArubaOS 10.3.0.0 through 10.3.1.0, any Aruba Instant version within the listed ranges, or any Siemens Scalance W1750d firmware, and has the web management interface exposed.
