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
Aruba Intelligent Edge Switch Series 2540, 2530, 2930F, 2930M, 2920, 5400R, and 3810M with firmware 16.08.* before 16.08.0009, 16.09.* before 16.09.0007, 16.10.* before 16.10.0003 are vulnerable to Remote Unauthorized Access in the WebUI.

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

Remote unauthorized access vulnerability in the WebUI of Aruba Intelligent Edge Switch Series 2540, 2530, 2930F, 2930M, 2920, 5400R, and 3810M with firmware versions prior to 16.08.0009, 16.09.0007, or 16.10.0003. An attacker could exploit this to gain unauthorized access to the switch management interface.

MitigationUpdate firmware to version 16.08.0009, 16.09.0007, 16.10.0003 or later. Restrict WebUI access to trusted networks or disable it if not needed.

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 your Aruba switch model
    Log into the switch CLI and run 'show system-information' or check the physical label to confirm the model is one of: 2540, 2530, 2930F, 2930M, 2920, 5400R, or 3810M
    Affected if The switch model is NOT one of the listed affected series
  2. Check the installed firmware version
    Log into the switch CLI and run 'show version' or 'show flash' to display the firmware version
    Affected if The switch model is one of the affected series AND the firmware version falls within the affected ranges (16.08.0 to <16.08.0009, 16.09.0 to <16.09.0007, or 16.10.0 to <16.10.0003)
  3. Determine if the WebUI is enabled
    Run 'show web-management' in the switch CLI to check if the WebUI feature is currently enabled
    Affected if WebUI is enabled on the switch (the vulnerability only affects switches with WebUI active)
  4. Assess WebUI network exposure
    Check the management VLAN configuration and access lists with 'show management' and 'show access-list' to see if the WebUI interface is reachable from untrusted networks
    Affected if The WebUI is accessible from outside trusted management networks

You are affected if you have an Aruba 2540, 2530, 2930F, 2930M, 2920, 5400R, or 3810M switch running firmware version 16.08.0-16.08.0008, 16.09.0-16.09.0006, or 16.10.0-16.10.0002 with the WebUI enabled and accessible.
