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
An unauthenticated Denial of Service (DoS) vulnerability exists in the handling of certain SSID strings by Aruba InstantOS and ArubaOS 10. Successful exploitation of this vulnerability results in the ability to interrupt the normal operation of the affected AP 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 InstantOS that address this security vulnerability.

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

An unauthenticated attacker can cause a Denial of Service on affected Aruba InstantOS and ArubaOS 10 access points by sending specially crafted SSID strings that trigger a crash or interruption in normal operation. The vulnerability lies in how the device handles certain SSID names.

MitigationApply the vendor-released upgrades for Aruba InstantOS (6.4.x, 6.5.x, 8.6.x, 8.7.x, 8.10.x) and ArubaOS 10.3.x to address this vulnerability. This is a firmware update to the affected access points.

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 device product and firmware version
    Log into the access point CLI or web interface and run 'show version' or check the system information page to identify the exact product name (ArubaOS, Aruba Instant, or Siemens Scalance W1750d) and firmware version.
    Affected if The device runs ArubaOS 10.3.0.0 through 10.3.1.0, Aruba Instant 6.4.x/6.5.x/8.6.x/8.7.x/8.10.x within the specified version ranges, or any version of Siemens Scalance W1750d.
  2. Verify ArubaOS version for CVE-2022-37894
    For ArubaOS devices, run 'show version' and check if the version falls within >= 10.3.0.0 and < 10.3.1.1. Compare your installed version number against this range.
    Affected if The installed ArubaOS version is 10.3.0.0 through 10.3.1.0 inclusive.
  3. Verify Aruba Instant version for CVE-2022-37894
    For Aruba Instant APs, run 'show version' or access the Instant UI and check the firmware version. Compare against the affected ranges: 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 The installed Aruba Instant version matches any of the listed affected version ranges.
  4. Confirm Siemens Scalance W1750d status
    Identify if the device is a Siemens Scalance W1750d by checking the product model number via 'show version' or the physical device label.
    Affected if The device is a Siemens Scalance W1750d running any firmware version.
  5. Check if SSID functionality is enabled
    Run 'show wlan ssid-profile' or access the wireless configuration section to verify if any SSIDs are configured and enabled on the access point.
    Affected if The access point has SSID profiles configured and enabled, making it susceptible to specially crafted SSID strings.

The environment is affected if the access point runs ArubaOS 10.3.0.0-10.3.1.0, any Aruba Instant version within the specified 6.4.x/6.5.x/8.6.x/8.7.x/8.10.x ranges, or any Siemens Scalance W1750d firmware, and has SSID functionality enabled.
