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 multiple underlying services that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba Networks AP management protocol) UDP port (8211). Successful exploitation of these vulnerabilities results in the ability to execute arbitrary code as a privileged user on the underlying operating system of Aruba InstantOS 6.4.x: 6.4.4.8-4.2.4.20 and below; Aruba InstantOS 6.5.x: 6.5.4.23 and below; Aruba InstantOS 8.6.x: 8.6.0.18 and below; Aruba InstantOS 8.7.x: 8.7.1.9 and below; Aruba InstantOS 8.10.x: 8.10.0.1 and below; ArubaOS 10.3.x: 10.3.1.0 and below; Aruba has released upgrades for Aruba InnstantOS that address these security vulnerabilities.

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 the PAPI (Aruba Networks AP management protocol) UDP port 8211 allows unauthenticated remote code execution as a privileged user by sending specially crafted packets. This affects multiple Aruba InstantOS and ArubaOS versions.

MitigationApply Aruba's released firmware upgrades for the affected InstantOS and ArubaOS versions listed in the advisory.

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 and firmware version
    Run 'show version' on Aruba devices or check the web UI for firmware version. For Siemens Scalance, check System > Device Information in the web interface.
    Affected if The device runs ArubaOS, Aruba Instant, or Siemens Scalance W1750d firmware.
  2. Compare the firmware version to the affected ranges
    For ArubaOS: check if version is >= 10.3.0.0 and < 10.3.1.1. For Aruba Instant: check if version falls in ranges 6.4.x, 6.5.x, 8.6.x, 8.7.x, or 8.10.x as listed in the advisory. For Siemens Scalance: all versions are affected.
    Affected if The firmware version matches any of the listed vulnerable version ranges.
  3. Verify if UDP port 8211 (PAPI service) is listening
    Run 'show ip interface' or check port status. On the CLI, use 'show running-config | include papi' or scan UDP port 8211 from an external host using 'nmap -sU -p 8211 <device_ip>'.
    Affected if UDP port 8211 is open and responding on the device.
  4. Confirm PAPI protocol is enabled
    Check the AP management settings in the web UI under Configuration > Access Points > AP System Profile, or run 'show ap database' to verify APs are managed via PAPI. The vulnerability applies when PAPI is actively handling AP management traffic.
    Affected if The device has APs configured and PAPI protocol is enabled for AP management on UDP 8211.

A device is affected if it runs a vulnerable ArubaOS/Instant version or any Siemens Scalance W1750d firmware, and UDP port 8211 (PAPI) is open and enabled for AP management.
