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 authenticated remote code execution vulnerabilities were discovered in the AOS-CX command line interface in Aruba CX 6200F Switch Series, Aruba 6300 Switch Series, Aruba 6400 Switch Series, Aruba 8320 Switch Series, Aruba 8325 Switch Series, Aruba 8400 Switch Series, Aruba CX 8360 Switch Series version(s): AOS-CX 10.06.xxxx: 10.06.0170 and below, AOS-CX 10.07.xxxx: 10.07.0050 and below, AOS-CX 10.08.xxxx: 10.08.1030 and below. Aruba has released upgrades for Aruba AOS-CX devices 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

Multiple authenticated remote code execution vulnerabilities exist in the AOS-CX command line interface on Aruba CX 6200F, 6300, 6400, 8320, 8325, 8400, and 8360 switch series. Authenticated users can execute arbitrary code by leveraging vulnerabilities in the CLI, likely through improper input validation or command injection.

MitigationUpgrade AOS-CX to version 10.06.0171 or higher for 10.06 branches, 10.07.0051 or higher for 10.07 branches, and 10.08.1031 or higher for 10.08 branches. Apply within planned maintenance windows following vendor upgrade procedures.

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 switch model
    Run 'show version' or 'show system information' from the CLI to retrieve the switch model number
    Affected if The model is NOT one of: CX 6200F, 6300, 6400, 8320, 8325, 8400, or 8360 (these are unaffected)
  2. Check AOS-CX software version
    Run 'show version' from the CLI and locate the 'Software version' or 'AOS-CX' version line
    Affected if The installed version falls within these ranges: 10.06.0001-10.06.0170, 10.07.0001-10.07.0020, or equals exactly 10.08.0001
  3. Verify CLI access is configured
    Run 'show running-config' and search for CLI-related lines, or check that management access includes CLI (port 22 for SSH or console)
    Affected if CLI access exists (this is required for the vulnerability to be exploitable)
  4. Confirm authentication method
    Check 'show aaa authentication' and review which authentication servers or local accounts are configured for CLI access
    Affected if Local accounts or authenticated users can access the CLI (the vulnerability requires an authenticated CLI session)

You are affected if your switch model is CX 6200F, 6300, 6400, 8320, 8325, 8400, or 8360 AND the AOS-CX version is within the affected ranges AND authenticated CLI access is enabled.

Upgrade available Upgrade to a release after 10.07.0020
Interim mitigation

Upgrade AOS-CX to version 10.06.0171 or higher for 10.06 branches, 10.07.0051 or higher for 10.07 branches, and 10.08.1031 or higher for 10.08 branches. Apply within planned maintenance windows following vendor upgrade procedures.

Recommended fix Moderate confidence

AOS-CX 10.06.0180 or later for 10.06 branch; AOS-CX 10.07.0030 or later for 10.07 branch; AOS-CX 10.08.1030 or latest 10.08.x for 10.08 branch

  1. 1. Identify the current AOS-CX version by running 'show version' in the CLI
  2. 2. Determine which branch (10.06.x, 10.07.x, or 10.08.x) the current version belongs to
  3. 3. For AOS-CX 10.06.x branch: upgrade to version 10.06.0171 or later (10.06.0180 recommended)
  4. 4. For AOS-CX 10.07.x branch: upgrade to version 10.07.0021 or later (10.07.0030 recommended)
  5. 5. For AOS-CX 10.08.x branch: upgrade to version 10.08.0002 or later (10.08.1030 or latest 10.08.xx recommended)
  6. 6. Download the appropriate firmware from the Aruba support portal (https://asp.arubanetworks.com)
  7. 7. Upload the firmware to the switch via 'copy tftp://<server>/<file> system: //
  8. 8. Execute 'boot system <image>' to set the new firmware as the boot image
Caveat Firmware upgrades may cause brief network disruption; ensure backup configuration is saved before upgrade; some configuration commands may differ between major.minor versions
