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 in a protocol-handling component of AOS-8 and AOS-10 Operating Systems. An unauthenticated attacker could exploit these vulnerabilities by sending specially crafted network messages to the affected service. Due to insufficient input validation, successful exploitation may terminate a critical system process, resulting in a denial-of-service condition.

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

A vulnerability in the protocol-handling component of Aruba AOS-8 and AOS-10 allows unauthenticated attackers to send specially crafted network messages that trigger insufficient input validation, causing termination of a critical system process and resulting in denial of service.

MitigationApply vendor patches when available; until then, restrict network access to affected services via firewall rules or access controls to limit exposure to untrusted networks.

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. Identify the installed ArubaOS version
    Execute `show version` or `show system info` on the Aruba controller CLI to retrieve the running firmware version
    Affected if The displayed version falls within any of these ranges: AOS-8: >= 6.5.4.0 to < 8.10.0.22, >= 8.11.0.0 to < 8.12.0.7, >= 8.13.0.0 to < 8.13.1.2; AOS-10: >= 10.4.0.0 to < 10.4.1.11, >= 10.5.0.0 to < 10.7.2.3; SD-WAN: 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
  2. Confirm the device model and software type
    Run `show inventory` or `show controller-info` to verify whether the device runs ArubaOS (AOS-8 or AOS-10) or SD-WAN software
    Affected if The device runs ArubaOS or SD-WAN firmware matching the affected version ranges identified in step 1
  3. Determine if protocol-handling services are active
    Review `show services` or `show ip interface brief` to confirm that protocol-handling components (such as management, control plane, or routing protocols) are enabled and listening on network interfaces
    Affected if Protocol-handling services are enabled and the device is reachable over the network on management or control plane ports

Your environment is affected if the installed ArubaOS or SD-WAN version falls within any of the affected version ranges AND the protocol-handling component is active and accessible on the network.

Upgrade available Upgrade to 8.10.0.22 / 8.12.0.7 / 8.13.1.2 or later
Fixed in 8.10.0.228.12.0.78.13.1.2
Interim mitigation

Apply vendor patches when available; until then, restrict network access to affected services via firewall rules or access controls to limit exposure to untrusted networks.

Recommended fix High confidence

ArubaOS: upgrade to 8.10.0.22+ (8.10.x), 8.12.0.7+ (8.11.x), 8.13.1.2+ (8.13.x), or 10.4.1.11+ (10.4.x) | SD-WAN: upgrade to latest available version beyond the vulnerable ranges

  1. 1. Identify the currently installed ArubaOS or SD-WAN version by running 'show version' on the controller CLI
  2. 2. For ArubaOS 6.5.4.0 through 8.10.x: upgrade to version 8.10.0.22 or later
  3. 3. For ArubaOS 8.11.x: upgrade to version 8.12.0.7 or later
  4. 4. For ArubaOS 8.13.x: upgrade to version 8.13.1.2 or later
  5. 5. For ArubaOS 10.4.x: upgrade to version 10.4.1.11 or later
  6. 6. For SD-WAN 8.6.0.4-2.2.x: upgrade to a version newer than 8.6.0.4-2.2.0.7
  7. 7. For SD-WAN 8.7.0.0-2.3.x: upgrade to a version newer than 8.7.0.0-2.3.0.9
  8. 8. Schedule upgrade during a maintenance window as upgrades may require controller reboot
Caveat Controller reboot is typically required after OS upgrade; ensure failover/cluster configuration handles this properly
