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 remote code execution vulnerability was discovered in the AOS-CX Network Analytics Engine (NAE) 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 10.07.xxxx: 10.07.0050 and below, AOS-CX 10.08.xxxx: 10.08.1030 and below, AOS-CX 10.09.xxxx: 10.09.0002 and below. Aruba has released upgrades for Aruba AOS-CX devices 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 remote code execution vulnerability in the AOS-CX Network Analytics Engine (NAE) allows an authenticated attacker to execute arbitrary code on affected Aruba CX switch series (6200F, 6300, 6400, 8320, 8325, 8400, 8360) running vulnerable AOS-CX versions 10.07.0050 and below, 10.08.1030 and below, or 10.09.0002 and below.

MitigationApply vendor-provided firmware upgrades to a supported AOS-CX version beyond the fixed releases for each branch (10.07.xxxx, 10.08.xxxx, 10.09.xxxx).

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 switch model
    Run 'show version' or 'show system' to confirm the switch model is one of: 6200F, 6300, 6400, 8320, 8325, 8400, or 8360
    Affected if The switch model matches one of the listed affected series
  2. Check the AOS-CX firmware version
    Run 'show version' and locate the firmware version string (for example, displayed as '10.07.xxxx' or '10.08.xxxx')
    Affected if The installed version falls within 10.07.0001-10.07.0050, 10.08.0001-10.08.1030, or 10.09.0001-10.09.0002
  3. Verify if Network Analytics Engine is enabled
    Run 'show nae status' or check the NAE configuration via 'show running-config | include nae'
    Affected if NAE is enabled and running on the device
  4. Confirm management network accessibility
    Check if the switch management interface or NAE service ports are reachable from untrusted networks using 'show ip interface brief' and review access control lists
    Affected if The switch management or NAE ports are exposed to network segments accessible by untrusted users

The device is affected if it is one of the listed switch models, runs a vulnerable AOS-CX version within the affected ranges, and has NAE enabled with potential network exposure.

dbcve · scoped
Upgrade available Upgrade to a release after 10.09.0002
Interim mitigation

Apply vendor-provided firmware upgrades to a supported AOS-CX version beyond the fixed releases for each branch (10.07.xxxx, 10.08.xxxx, 10.09.xxxx).

Recommended fix Moderate confidence

AOS-CX version > 10.07.0050 (10.7 branch), > 10.08.1030 (10.8 branch), or > 10.09.0002 (10.9 branch) - or migrate to latest stable release

  1. 1. Identify the current AOS-CX version by running 'show version' on the switch
  2. 2. Determine which vulnerable version branch your device is running (10.07.x, 10.08.x, or 10.09.x)
  3. 3. Access Aruba's support portal or official firmware download page at www.arubanetworks.com
  4. 4. Download the latest AOS-CX firmware for your specific switch model that is newer than the last vulnerable version in your branch
  5. 5. Upload the firmware to the switch using 'upload firmware <filename>' command
  6. 6. Verify the firmware upload completed successfully
  7. 7. Reboot the switch to apply the new firmware using 'reload' command
  8. 8. After reboot, confirm the new version is installed by running 'show version'
Caveat Firmware upgrades may cause brief network disruption; test in lab environment before production deployment; review release notes for any configuration changes
