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
Stack-based buffer overflow vulnerabilities exist in several underlying management service components accessed through the command-line interface of the AOS-8 and AOS-10 Operating Systems. An authenticated attacker with administrative privileges could exploit these vulnerabilities by sending specially crafted requests to the affected services. Successful exploitation could allow the attacker to execute arbitrary code with elevated privileges on the underlying operating system.

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

Stack-based buffer overflow vulnerabilities in management service components accessed through the CLI of Aruba AOS-8 and AOS-10 operating systems allow an authenticated attacker with administrative privileges to send specially crafted requests and achieve arbitrary code execution with elevated system privileges.

MitigationApply Aruba-supplied security patches for AOS-8 and AOS-10; until patches are available, limit CLI access to trusted administrative users only and monitor for suspicious CLI activity.

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 installed ArubaOS version
    Run 'show version' or 'show system information' in the CLI to display the active firmware version
    Affected if The displayed version falls within any of these ranges: >= 6.5.4.0 and < 8.10.0.22; OR >= 8.11.0.0 and < 8.12.0.7; OR >= 8.13.0.0 and < 8.13.1.2; OR >= 10.4.0.0 and < 10.4.1.11; OR >= 10.5.0.0 and < 10.7.2.3
  2. Identify installed SD-WAN version
    Run 'show version' or 'show sd-wan version' in the CLI to display the active SD-WAN firmware version
    Affected if The displayed version falls within these ranges: >= 8.6.0.4-2.2.0.0 through <= 8.6.0.4-2.2.0.7; OR >= 8.7.0.0-2.3.0.0 through <= 8.7.0.0-2.3.0.9
  3. Confirm CLI access is enabled
    Check if SSH or console CLI access is configured by running 'show ip ssh' or examining management interface settings
    Affected if CLI access is enabled and reachable over network (SSH on port 22) or console
  4. Verify administrative user accounts exist
    Run 'show user-database' or 'show aaa authentication local' to list administrative accounts configured on the device
    Affected if One or more administrative accounts with privileges to access management service CLI are present

You are affected if your device runs ArubaOS or SD-WAN versions within the affected ranges listed above AND the CLI management service is accessible with administrative credentials.
