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
Unauthenticated Denial-of-Service (DoS) vulnerabilities exist in the AP Management service accessed via the PAPI protocol. Successful exploitation of these vulnerabilities results in the ability to interrupt the normal operation of the affected service.

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

Unauthenticated attackers can exploit vulnerabilities in the AP Management service accessed via the PAPI protocol to cause denial-of-service conditions, allowing interruption of normal service operation without requiring authentication.

MitigationRestrict network access to the AP Management service and PAPI protocol interface; apply vendor patches when available; implement rate limiting and monitoring for anomalous traffic patterns.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 version
    Run the command to display the system version (for example, 'show version' or 'show controller-info' in the Aruba CLI). Compare the displayed version number against the affected ranges: 8.10.0.0 through 8.10.0.10, 8.11.0.0 through 8.11.2.1, 10.4.0.0 through 10.4.1.0, and 10.5.0.0 through 10.5.1.0.
    Affected if The installed version falls within any of the listed version ranges.
  2. Verify PAPI protocol status
    Determine whether the PAPI (Protocol for AP) protocol is enabled on the controller. This may be checked via the configuration interface, command output (for example, 'show papi status' or similar), or by reviewing the running configuration for PAPI-related settings.
    Affected if The PAPI protocol is enabled and operational on the device.
  3. Assess network exposure of AP Management service
    Review network accessibility of the AP Management service and PAPI interface. Check firewall rules, ACLs, or interface bindings to determine if the PAPI port (typically UDP port 8211) is exposed to untrusted networks or the internet.
    Affected if The AP Management service via PAPI is reachable from untrusted or external networks without proper access controls.

A user is affected if their ArubaOS version is within the vulnerable ranges AND the PAPI protocol is enabled and accessible from a network where unauthenticated attackers could reach it.

Upgrade available Upgrade to a release after 10.5.1.0
Interim mitigation

Restrict network access to the AP Management service and PAPI protocol interface; apply vendor patches when available; implement rate limiting and monitoring for anomalous traffic patterns.

Recommended fix Moderate confidence

ArubaOS 8.10.0.11+, 8.11.3.0+, 10.4.2.0+, or 10.5.2.0+ (depending on current version branch)

  1. 1. Identify the current ArubaOS version running on the affected device using 'show version' command
  2. 2. Based on the affected version range, upgrade to a version higher than the last affected version in the range: For 8.10.x, upgrade to 8.10.0.11 or later; For 8.11.x, upgrade to 8.11.3.0 or later; For 10.4.x, upgrade to 10.4.2.0 or later; For 10.5.x, upgrade to 10.5.2.0 or later
  3. 3. Download the appropriate upgrade image from the Aruba support portal (https://asp.arubanetworks.com)
  4. 4. Back up the current configuration using 'backup flash' command
  5. 5. Upload the new firmware image to the device via TFTP, FTP, or WebUI
  6. 6. Execute 'upgrade-software' command to install the new image
  7. 7. Reload the device using 'reload' command after upgrade completes
  8. 8. Verify the new version is installed using 'show version' and confirm the PAPI service is operational
