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
There are buffer overflow vulnerabilities in the underlying Central Communications service that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba's Access Point management protocol) UDP port (8211). Successful exploitation of these vulnerabilities result in the ability to execute arbitrary code as a privileged user 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 · high confidence

Buffer overflow vulnerability in Aruba's Central Communications service allowing unauthenticated remote code execution via specially crafted packets to PAPI UDP port 8211 (the Access Point management protocol). Successful exploitation grants arbitrary code execution as a privileged user on the underlying OS.

MitigationApply vendor-supplied patches immediately. Until patched, restrict network access to UDP port 8211 using firewalls or network segmentation to limit exposure 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 the installed ArubaOS or InstantOS version
    Run 'show version' on the Aruba controller or access point CLI, or check the web UI dashboard for the firmware version
    Affected if The version falls within >= 10.3.0.0 and < 10.4.1.1, OR >= 10.5.0.0 and < 10.4.1.1, OR >= 6.4.0.0 and < 8.6.0.24, OR >= 8.7.0.0 and < 8.10.0.11
  2. Verify if UDP port 8211 is listening or exposed
    Run 'show ip interface' to list all listening services, or use 'netstat -anu | grep 8211' or 'ss -uan | grep 8211' to check if UDP port 8211 is bound to an interface
    Affected if UDP port 8211 is open and listening on any interface accessible from untrusted networks
  3. Confirm the PAPI service status
    Check if the PAPI (Access Point Management Protocol) service is enabled by running 'show process' or reviewing the service configuration in the Aruba Central dashboard or local controller CLI
    Affected if The PAPI service is running and bound to a network interface reachable from outside the trusted network

You are affected if your device runs a vulnerable ArubaOS or InstantOS version AND has UDP port 8211 exposed to untrusted networks with the PAPI service enabled.

Fixed in 8.6.0.248.10.0.1110.4.1.1
Interim mitigation

Apply vendor-supplied patches immediately. Until patched, restrict network access to UDP port 8211 using firewalls or network segmentation to limit exposure to untrusted networks.

Recommended fix High confidence

ArubaOS 10.4.1.1+ (for 10.3.x branch) or 10.5.1.1+ (for 10.5.x branch); InstantOS 8.6.0.24+ (for 6.4.x branch) or 8.10.0.11+ (for 8.7.x branch)

  1. 1. Identify the currently installed ArubaOS or InstantOS version by accessing the device CLI or web interface
  2. 2. For ArubaOS 10.3.x versions: Upgrade to version 10.4.1.1 or later
  3. 3. For ArubaOS 10.5.x versions: Upgrade to version 10.5.1.1 or later
  4. 4. For InstantOS 6.4.x versions: Upgrade to version 8.6.0.24 or later
  5. 5. For InstantOS 8.7.x versions: Upgrade to version 8.10.0.11 or later
  6. 6. Download the appropriate firmware from the official Aruba Networks support portal (support.arubanetworks.com)
  7. 7. Upload the firmware through the device management interface or via console/TFTP
  8. 8. Verify the upgrade completes successfully and the device is operational
Caveat Major version upgrades may require configuration review; ensure backup of configuration before upgrading; some feature changes may occur between major/minor releases
