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

A remote arbitrary command execution vulnerability in Aruba SD-WAN Software and Gateways and ArubaOS allows authenticated or unauthenticated remote attackers to execute arbitrary commands on affected devices, likely through improper input validation or authentication bypass in the SD-WAN management interface or gateway firmware.

MitigationApply vendor-released patches for affected versions: upgrade to 8.6.0.4-2.2.0.6 or later for the 8.6.x branch; upgrade to 8.7.1.4, 8.6.0.7, 8.5.0.12, or 8.3.0.16 or later for respective branches as specified in the Aruba security 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 product type
    Determine if the device is running Aruba SD-WAN, ArubaOS, or Siemens Scalance W1750d. Check the system firmware or management interface for the product name.
    Affected if The product is Aruba SD-WAN, ArubaOS, or Siemens Scalance W1750d
  2. Check Aruba SD-WAN version
    Access the SD-WAN management interface or use CLI command 'show version' to retrieve the installed software version.
    Affected if Version is >= 2.2.0.0 and < 2.2.0.6
  3. Check ArubaOS version
    Access the device CLI or web interface and run 'show version' or check the system information page to determine the ArubaOS version.
    Affected if Version falls within any of these ranges: >= 8.3.0.0 and < 8.3.0.16, OR >= 8.5.0.0 and < 8.5.0.12, OR >= 8.6.0.0 and < 8.6.0.6, OR >= 8.7.0.0 and < 8.7.1.4
  4. Check Siemens Scalance W1750d firmware version
    Access the device web interface or CLI and check the firmware version information.
    Affected if Any version of Siemens Scalance W1750d firmware is installed

The environment is affected if the device runs Aruba SD-WAN version 2.2.0.0 to 2.2.0.5, ArubaOS versions 8.3.0.0-8.3.0.15, 8.5.0.0-8.5.0.11, 8.6.0.0-8.6.0.5, or 8.7.0.0-8.7.1.3, or any version of Siemens Scalance W1750d firmware.
