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 stack-based buffer overflow vulnerabilities that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba Networks 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

Stack-based buffer overflow vulnerability in Aruba Networks access point management protocol (PAPI) allows unauthenticated attackers to send specially crafted UDP packets to port 8211 and achieve remote code execution as a privileged user.

MitigationApply vendor-supplied firmware updates for affected Aruba access point and controller products to patch the PAPI buffer overflow vulnerability.

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 product type
    Determine if the device runs ArubaOS or Aruba SD-WAN software. Check the system prompt, CLI output such as 'show version', or the product model number.
    Affected if The device is an Aruba Networks access point, controller, or SD-WAN appliance running the software variants listed in the affected versions.
  2. Determine the installed firmware version
    Run 'show version' in the CLI or check the web management interface for the current firmware build number. Note that version strings may include both a base version and a build suffix (for example, 8.6.0.19, 8.10.0.4, 10.3.1.0, or 8.7.0.0-2.3.0.8).
    Affected if The installed version falls within any of these ranges: ArubaOS 8.6.0.0 to 8.6.0.19, 8.10.0.0 to 8.10.0.4, or 10.3.0.0 to 10.3.1.0; or SD-WAN version 8.7.0.0-2.3.0.0 through 8.7.0.0-2.3.0.8.
  3. Verify if the PAPI protocol is enabled
    Check if UDP port 8211 (the PAPI service) is listening on the device. Use 'show ip interface' or a port scan tool targeting the management IP addresses. In the CLI, run 'show process' or check the PAPI process status if available.
    Affected if UDP port 8211 is open and accepting packets on any management interface.
  4. Assess network exposure of the management interface
    Review the network configuration to determine if the management interface (or any interface with PAPI enabled) is reachable from untrusted networks. Check interface IP assignments, ACLs, and whether the device is directly internet-facing.
    Affected if The management interface with PAPI (port 8211/UDP) is accessible from external networks or untrusted VLANs without proper filtering.

The device is affected if it runs an ArubaOS or SD-WAN version within the affected ranges and has PAPI (UDP port 8211) enabled on an accessible management interface.
