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 vulnerabilities exist in Aruba's Central Communications service for the PAPI protocol (UDP port 8211). Attackers can send specially crafted packets to achieve unauthenticated remote code execution as a privileged user.

MitigationApply available Aruba firmware patches immediately; if patches are unavailable, restrict network access to UDP port 8211 using firewalls or network segmentation to prevent untrusted sources from reaching the PAPI service.

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 product
    Run 'show version' on the device CLI or check the system information via the web interface
    Affected if The device is not ArubaOS or HP InstantOS
  2. Determine the firmware version
    Execute 'show version' in the device CLI or retrieve the OS version from the web management interface
    Affected if The version falls within >= 10.3.0.0 and < 10.4.1.1, OR >= 10.5.0.0 and < 10.5.1.1 for ArubaOS; OR >= 6.4.0.0 and < 8.6.0.24, OR >= 8.7.0.0 and < 8.10.0.11 for HP InstantOS
  3. Verify if UDP port 8211 is listening
    Run 'show ip ports' or use 'netstat -anu | grep 8211' to check if the PAPI service port is open
    Affected if UDP port 8211 is open and accepting connections
  4. Confirm PAPI protocol is enabled
    Check the device configuration for 'papi' or 'central-communications' settings via 'show running-config' or the web interface
    Affected if The PAPI protocol or Central Communications service is enabled

The device is affected if it runs a vulnerable ArubaOS or HP InstantOS version AND has UDP port 8211 open with the PAPI service enabled.

Upgrade available Upgrade to 8.6.0.24 / 8.10.0.11 / 10.4.1.1 or later
Fixed in 8.6.0.248.10.0.1110.4.1.1
Interim mitigation

Apply available Aruba firmware patches immediately; if patches are unavailable, restrict network access to UDP port 8211 using firewalls or network segmentation to prevent untrusted sources from reaching the PAPI service.

Recommended fix High confidence

ArubaOS 10.4.1.1+ or 10.5.1.1+ / InstantOS 8.6.0.24+ or 8.10.0.11+

  1. Identify the exact ArubaOS or InstantOS version currently running on the affected device
  2. For ArubaOS devices: Upgrade to version 10.4.1.1 or higher if running 10.3.x, or upgrade to version 10.5.1.1 or higher if running 10.5.x
  3. For InstantOS devices: Upgrade to version 8.6.0.24 or higher if running 6.4.x-8.6.x, or upgrade to version 8.10.0.11 or higher if running 8.7.x-8.10.x
  4. Obtain the upgrade image from Aruba's official support portal (support.hpe.com or www.arubanetworks.com)
  5. Follow Aruba's standard upgrade procedure for your deployment model - either via CLI, AirWave, or Central
  6. After upgrade, verify the PAPI service (UDP port 8211) is running and the version is correct
  7. Test that normal AP management and controller functions are operational
Caveat Upgrading between major version branches may require downtime and could have behavioral changes - review Aruba's release notes before upgrading
