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
Multiple unauthenticated Denial-of-Service (DoS) vulnerabilities exist in the Soft AP daemon accessed via the PAPI protocol. Successful exploitation of these vulnerabilities results in the ability to interrupt the normal operation of the affected Access Point.

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

Multiple unauthenticated DoS vulnerabilities exist in the Soft AP daemon accessed via the PAPI protocol. An attacker can exploit these vulnerabilities without authentication to crash or disrupt the normal operation of the affected Access Point, likely through malformed or specially crafted PAPI protocol packets causing the daemon to fail or enter an error state.

MitigationImplement authentication and authorization checks on the PAPI protocol interface, add rate limiting and input validation to the Soft AP daemon, and apply vendor-provided firmware updates when available.

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

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 'show version' or check the controller WebUI for the firmware version
    Affected if Version is >= 10.4.0.0 and < 10.4.1.2, or equals 10.6.0.0
  2. Identify the installed HP InstantOS version
    Run 'show version' or check the Instant AP WebUI for the firmware version
    Affected if Version is >= 8.10.0.0 and < 8.10.0.13, or >= 8.12.0.0 and < 8.12.0.2
  3. Confirm if Soft AP daemon is running
    Check process status via 'show process' or log into the AP and run 'show process' to verify the Soft AP daemon is active
    Affected if The Soft AP daemon process is running on the device
  4. Verify PAPI protocol interface is exposed
    Check network configuration to determine if the PAPI port (UDP 8211) is accessible on management or control plane interfaces
    Affected if PAPI protocol interface is reachable from untrusted networks without authentication

You are affected if your ArubaOS version falls within 10.4.0.0 to 10.4.1.1 or equals 10.6.0.0, or your InstantOS version falls within 8.10.0.0 to 8.10.0.12 or 8.12.0.0 to 8.12.0.1, AND the Soft AP daemon is running with an exposed PAPI interface.

Upgrade available Upgrade to 8.10.0.13 / 8.12.0.2 / 10.4.1.2 or later
Fixed in 8.10.0.138.12.0.210.4.1.2
Interim mitigation

Implement authentication and authorization checks on the PAPI protocol interface, add rate limiting and input validation to the Soft AP daemon, and apply vendor-provided firmware updates when available.

Recommended fix High confidence

ArubaOS: 10.4.1.2+ or 10.6.1.0+; InstantOS: 8.10.0.13+ or 8.12.0.2+

  1. 1. Identify the current ArubaOS or InstantOS version running on affected Access Points
  2. 2. For ArubaOS 10.4.x versions: Plan upgrade to version 10.4.1.2 or later
  3. 3. For ArubaOS 10.6.0.0: Plan upgrade to version 10.6.1.0 or later (first stable release after 10.6.0.0)
  4. 4. For InstantOS 8.10.x versions: Plan upgrade to version 8.10.0.13 or later
  5. 5. For InstantOS 8.12.x versions: Plan upgrade to version 8.12.0.2 or later
  6. 6. Schedule maintenance window for upgrade (DoS vulnerability may cause service interruption)
  7. 7. Backup current configuration before performing upgrade
  8. 8. Upgrade APs via Aruba's management interface (AirWave, Central, or local CLI)
Caveat Standard upgrade risks apply - ensure configuration compatibility and test in staging environment before production deployment
