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

Critical buffer overflow vulnerabilities in the PAPI (Aruba Networks AP management protocol) on UDP port 8211 allow unauthenticated remote attackers to execute arbitrary code as a privileged user by sending specially crafted packets. The vulnerabilities affect multiple Aruba InstantOS and ArubaOS versions.

MitigationApply vendor-supplied firmware upgrades to a patched version: Aruba InstantOS 6.4.x to 6.4.4.8-4.2.4.21 or later; 6.5.x to 6.5.4.24 or later; 8.6.x to 8.6.0.19 or later; 8.7.x to 8.7.1.10 or later; 8.10.x to 8.10.0.2 or later; ArubaOS 10.3.x to 10.3.1.1 or later.

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 is running ArubaOS, Aruba Instant, or Siemens Scalance W1750d firmware
    Affected if Device is one of these three product families
  2. Verify PAPI service is enabled
    Check if UDP port 8211 (PAPI) is listening or exposed on the device
    Affected if PAPI service on UDP port 8211 is active and reachable
  3. Check ArubaOS version
    Retrieve the installed ArubaOS firmware version and compare to the affected range: >= 10.3.0.0 and < 10.3.1.1
    Affected if Version falls within 10.3.0.0 through 10.3.1.0
  4. Check Aruba Instant version
    Retrieve the installed Aruba InstantOS version and compare to any affected range: 6.4.0.0 to < 6.4.4.8-4.2.4.21, 6.5.0.0 to < 6.5.4.24, 8.6.0.0 to < 8.6.0.19, 8.7.0.0 to < 8.7.1.10, or 8.10.0.0 to < 8.10.0.2
    Affected if Version falls within any of these ranges
  5. Confirm Siemens Scalance model
    Identify if the device is a Siemens Scalance W1750d model
    Affected if Device is a Siemens Scalance W1750d (all versions are affected)

The environment is affected if the device runs an affected Aruba product or Siemens Scalance W1750d, has PAPI on UDP port 8211 enabled, and the installed version falls within the specified vulnerable ranges.

Upgrade available Upgrade to 6.4.4.8-4.2.4.21 / 6.5.4.24 / 8.6.0.19 or later
Fixed in 6.4.4.8-4.2.4.216.5.4.248.6.0.19
Interim mitigation

Apply vendor-supplied firmware upgrades to a patched version: Aruba InstantOS 6.4.x to 6.4.4.8-4.2.4.21 or later; 6.5.x to 6.5.4.24 or later; 8.6.x to 8.6.0.19 or later; 8.7.x to 8.7.1.10 or later; 8.10.x to 8.10.0.2 or later; ArubaOS 10.3.x to 10.3.1.1 or later.

Recommended fix High confidence

Aruba InstantOS: 6.4.4.8-4.2.4.21+, 6.5.4.24+, 8.6.0.19+, 8.7.1.10+, 8.10.0.2+ | ArubaOS: 10.3.1.1+

  1. 1. Identify the exact Aruba InstantOS or ArubaOS version currently running on the affected device.
  2. 2. For Aruba InstantOS 6.4.x: Upgrade to version 6.4.4.8-4.2.4.21 or later.
  3. 3. For Aruba InstantOS 6.5.x: Upgrade to version 6.5.4.24 or later.
  4. 4. For Aruba InstantOS 8.6.x: Upgrade to version 8.6.0.19 or later.
  5. 5. For Aruba InstantOS 8.7.x: Upgrade to version 8.7.1.10 or later.
  6. 6. For Aruba InstantOS 8.10.x: Upgrade to version 8.10.0.2 or later (the description mentions 8.10.0.1 and below are vulnerable, so the fix would be 8.10.0.2+).
  7. 7. For ArubaOS 10.3.x: Upgrade to version 10.3.1.1 or later.
  8. 8. For Scalance W1750d: If firmware updates are available from Siemens, apply them; otherwise implement network segmentation to isolate the device.
Caveat Review Aruba upgrade documentation for migration considerations; ensure backup before upgrade
