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
Vulnerabilities exist which allow an authenticated attacker to access sensitive information on the ArubaOS command line interface. Successful exploitation could allow access to data beyond what is authorized by the users existing privilege level.

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 · moderate confidence

This is a privilege escalation vulnerability in ArubaOS that allows an authenticated attacker to access sensitive information via the command line interface beyond what their current privilege level authorizes. The attacker needs valid credentials to exploit this, but can then view data they shouldn't have access to.

MitigationApply the vendor-supplied ArubaOS patch when available. In the interim, limit CLI access to trusted personnel only and enforce least-privilege access controls to reduce the attack surface.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Check ArubaOS version
    Run 'show version' or 'show system information' in the CLI to display the installed ArubaOS version
    Affected if The displayed version falls within any of these ranges: >= 6.5.4.0 and < 8.6.0.21, >= 8.7.0.0 and < 8.10.0.7, >= 8.11.0.0 and < 8.11.1.1, or >= 10.4.0.0 and < 10.4.0.2
  2. Confirm CLI access is enabled
    Run 'show running-config | include cli' or check the configuration for any CLI management settings that allow authenticated access
    Affected if CLI access is permitted for users with any privilege level
  3. Identify privilege assignments
    Run 'show user' or 'show privilege' to see which users have what privilege levels, and check if lower-privilege users exist
    Affected if There are users with limited privilege levels who could potentially escalate beyond their authorized access

If the ArubaOS version is in any of the affected version ranges and the CLI is accessible to authenticated users, the environment is vulnerable to CVE-2023-35976.

Upgrade available Upgrade to 8.6.0.21 / 8.10.0.7 / 8.11.1.1 or later
Fixed in 8.6.0.218.10.0.78.11.1.1
Interim mitigation

Apply the vendor-supplied ArubaOS patch when available. In the interim, limit CLI access to trusted personnel only and enforce least-privilege access controls to reduce the attack surface.

Recommended fix Moderate confidence

Upgrade to ArubaOS 8.6.0.21, 8.10.0.7, 8.11.1.1, or 10.4.0.2 (depending on your current major version branch)

  1. Review the current ArubaOS version by running 'show version' on the CLI
  2. Confirm the current version falls within one of the affected ranges: 6.5.4.0-8.6.0.20, 8.7.0.0-8.10.0.6, 8.11.0.0-8.11.1.0, or 10.4.0.0-10.4.0.1
  3. Download the appropriate fixed version from the Aruba support portal (www.arubanetworks.com): 8.6.0.21, 8.10.0.7, 8.11.1.1, or 10.4.0.2
  4. Upload the firmware to the Aruba controller via the CLI or WebUI
  5. Schedule a maintenance window as upgrades require controller downtime
  6. Execute the upgrade via 'upgrade-software' command or through the WebUI
  7. Reboot the controller after upgrade completes
  8. Verify the new version is running with 'show version'
Caveat Standard ArubaOS upgrade procedures apply - ensure backups are taken and test in non-production environment first
