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
An authenticated command injection vulnerability exists in the Aruba InstantOS and ArubaOS 10 command line interface. Successful exploitation of this vulnerability results in the ability to execute arbitrary commands as a privileged user 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 InstantOS that address this security vulnerability.

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

Authenticated command injection vulnerability in Aruba InstantOS and ArubaOS command line interface allows an authenticated attacker to execute arbitrary commands as a privileged (root) user on the underlying operating system due to insufficient input validation in CLI commands.

MitigationUpgrade to patched versions of Aruba InstantOS (6.4.4.8-4.2.4.21+, 6.5.4.24+, 8.6.0.19+, 8.7.1.10+, 8.10.0.2+) and ArubaOS 10.3.1.1+ as specified in the Aruba security advisory.

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 device product and model
    Access the device CLI or web interface and run 'show version' or check the system information page to identify if the device is Aruba Instant, ArubaOS, or Siemens Scalance W1750d
    Affected if The device is Aruba Instant, ArubaOS, or Siemens Scalance W1750d
  2. Check ArubaOS version
    Run 'show version' in the ArubaOS CLI and note the software version number
    Affected if The installed ArubaOS version is 10.3.0.0 through 10.3.1.0 (anything >= 10.3.0.0 but < 10.3.1.1)
  3. Check Aruba Instant version
    Run 'show version' in the Aruba Instant CLI and note the software version number
    Affected if The installed Aruba Instant version falls within any of these ranges: >= 6.4.0.0 but < 6.4.4.8-4.2.4.21, >= 6.5.0.0 but < 6.5.4.24, >= 8.6.0.0 but < 8.6.0.19, >= 8.7.0.0 but < 8.7.1.10, or >= 8.10.0.0 but < 8.10.0.2
  4. Check Siemens Scalance W1750d firmware version
    Access the Scalance W1750d web interface or CLI and identify the firmware version
    Affected if Any firmware version is installed (all versions of this device are affected)
  5. Verify CLI access is available
    Confirm the device CLI is accessible via console, SSH, or telnet (the vulnerability requires an authenticated CLI session to exploit)
    Affected if CLI access exists and the device version matches the affected ranges above

The device is affected if it is running ArubaOS < 10.3.1.1, Aruba Instant in any of the listed affected version ranges, or any version of Siemens Scalance W1750d firmware, and the CLI interface is accessible for authenticated exploitation.
