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

This is a denial-of-service vulnerability in the protocol-handling component of Aruba AOS-8 and AOS-10 operating systems. An unauthenticated remote attacker can exploit insufficient input validation in the affected service by sending specially crafted network messages, causing a critical system process to terminate and resulting in service disruption.

MitigationApply the vendor-supplied patches for AOS-8 and AOS-10 as soon as they become available. If immediate patching is not possible, consider network segmentation to limit exposure of the affected protocol-handling services to untrusted networks.

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
    Execute 'show version' or 'show system information' on the Aruba device CLI
    Affected if The version displayed falls within any of these ranges: >= 6.5.4.0 and < 8.10.0.22; >= 8.11.0.0 and < 8.12.0.7; >= 8.13.0.0 and < 8.13.1.2; >= 10.4.0.0 and < 10.4.1.11; >= 10.5.0.0 and < 10.7.2.3
  2. Identify installed SD-WAN version
    Execute 'show version' or 'show sd-wan version' on the SD-WAN appliance CLI
    Affected if The version displayed falls within: >= 8.6.0.4-2.2.0.0 and <= 8.6.0.4-2.2.0.7, or >= 8.7.0.0-2.3.0.0 and <= 8.7.0.0-2.3.0.9
  3. Verify protocol-handling service is exposed
    Check if the protocol-handling service (the vulnerable component) is accessible from untrusted network interfaces by reviewing 'show ip interface' and firewall policies
    Affected if The service is bound to or accessible via interfaces in untrusted network segments (such as DMZ, guest, or internet-facing VLANs)

The environment is affected if the device runs an ArubaOS or SD-WAN version within the affected ranges AND the protocol-handling service is exposed to untrusted networks.

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 the vendor-supplied patches for AOS-8 and AOS-10 as soon as they become available. If immediate patching is not possible, consider network segmentation to limit exposure of the affected protocol-handling services to untrusted networks.

Recommended fix High confidence

ArubaOS: 8.10.0.22+, 8.12.0.7+, 8.13.1.2+, or 10.4.1.11+ | SD-WAN: >8.6.0.4-2.2.0.7 or >8.7.0.0-2.3.0.9

  1. 1. Identify the current ArubaOS or SD-WAN version running on the affected device using 'show version' command
  2. 2. For ArubaOS 8.x: Upgrade to version 8.10.0.22 or later if running 8.10.x; upgrade to 8.12.0.7 or later if running 8.11.x; upgrade to 8.13.1.2 or later if running 8.13.x
  3. 3. For ArubaOS 10.x: Upgrade to version 10.4.1.11 or later if running 10.4.x
  4. 4. For SD-WAN: Upgrade to a version greater than 8.6.0.4-2.2.0.7 if running the 8.6.0.4-2.2.x branch, or greater than 8.7.0.0-2.3.0.9 if running the 8.7.0.0-2.3.x branch
  5. 5. Download the appropriate upgrade image from support.hpe.com and upload to the device controller
  6. 6. Execute the upgrade following standard Aruba upgrade procedures: 'upgrade-software' or via the WebUI under Maintenance > Software
  7. 7. After upgrade, verify the new version is running and confirm the vulnerability is remediated
Caveat Review Aruba upgrade release notes for known issues; ensure controller redundancy and backup before upgrading
