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 attacker can impact the integrity of the ArubaOS bootloader on 7xxx series controllers. Successful exploitation can compromise the hardware chain of trust on the impacted controller.

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 vulnerability allows an authenticated attacker to modify the ArubaOS bootloader on 7000 series controllers, compromising the hardware chain of trust. The attacker with valid credentials can impact bootloader integrity, potentially enabling persistent firmware-level compromises.

MitigationApply Aruba's firmware updates for this vulnerability. Restrict administrative access to trusted personnel and monitor for unauthorized authentication attempts.

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 installed ArubaOS or SD-WAN version
    Run the command 'show version' on the controller CLI or check the web UI dashboard for the firmware version information
    Affected if The displayed version falls within any of these ranges: 6.5.4.0 to 6.5.4.21, 8.4.0.0 to 8.6.0.16, 8.7.0.0 to 8.7.1.8, 8.8.0.0 to 10.3.0.0, or for SD-WAN: 8.7.0.0-2.3.0.0 to 8.7.0.0-2.3.0.5
  2. Confirm the hardware model is a 7000 series controller
    Run the command 'show inventory' or 'show controller-info' on the device CLI to identify the hardware platform
    Affected if The device is an Aruba 7000 series controller (such as 7005, 7008, 7010, 7024, or 7030) and the firmware version is in the affected ranges from step 1
  3. Verify bootloader integrity
    If you have CLI access, run 'show boot-params' or 'show bootloader version' to inspect the current bootloader configuration and version
    Affected if The bootloader version is inconsistent with the expected version for your ArubaOS release or shows signs of unauthorized modification
  4. Review administrative access logs
    Check system logs using 'show log system' or review authentication logs for any unexpected administrative logins, especially from unfamiliar IP addresses or during unusual hours
    Affected if There are administrative login events from untrusted accounts or unauthorized sources that may indicate credential compromise

You are affected if your device is a 7000 series controller running ArubaOS or SD-WAN firmware version within the affected ranges listed above, combined with the possibility of unauthorized administrative access.

Fixed in 6.5.4.228.6.0.178.7.0.0-2.3.0.6
Interim mitigation

Apply Aruba's firmware updates for this vulnerability. Restrict administrative access to trusted personnel and monitor for unauthorized authentication attempts.

Recommended fix Moderate confidence

Upgrade to the minimum fixed version for your product line: Sd Wan 8.7.0.0-2.3.0.6+, ArubaOS 6.5.4.22+, 8.6.0.17+, 8.7.1.9+, or 10.3.0.1+

  1. Identify the specific ArubaOS or Sd Wan product and current version running on the controller
  2. Determine which version branch the current installation belongs to (6.5.4.x, 8.4.x-8.6.x, 8.7.x, or 8.8.x-10.x)
  3. For Sd Wan: upgrade to version 8.7.0.0-2.3.0.6 or later
  4. For ArubaOS 6.5.4.x: upgrade to version 6.5.4.22 or later
  5. For ArubaOS 8.4.x-8.6.x: upgrade to version 8.6.0.17 or later
  6. For ArubaOS 8.7.x: upgrade to version 8.7.1.9 or later
  7. For ArubaOS 8.8.x-10.x: upgrade to version 10.3.0.1 or later
  8. Follow standard Aruba upgrade procedures including backup of configuration
