CVE-2021-29143
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 · uneditedA remote execution of arbitrary commands vulnerability was discovered in Aruba CX 6200F Switch Series, Aruba 6300 Switch Series, Aruba 6400 Switch Series, Aruba 8320 Switch Series, Aruba 8325 Switch Series, Aruba 8400 Switch Series, Aruba CX 8360 Switch Series version(s): Aruba AOS-CX firmware: 10.04.xxxx - versions prior to 10.04.3070, 10.05.xxxx - versions prior to 10.05.0070, 10.06.xxxx - versions prior to 10.06.0110, 10.07.xxxx - versions prior to 10.07.0001.

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 confidenceA remote code execution vulnerability in Aruba AOS-CX firmware allows authenticated attackers to execute arbitrary commands on affected switch devices. The vulnerability affects multiple switch series running firmware versions prior to the fixed releases.
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 checksWork through these to decide whether this CVE applies to you.
-
Identify the switch modelLog into the switch CLI and run 'show version' or check the device型号 to confirm it is an Aruba AOS-CX switchAffected if The device is not an Aruba AOS-CX switch - this CVE does not apply
-
Determine the installed firmware versionExecute 'show version' in the switch CLI and locate the firmware version string (typically displayed as something like 10.04.xxxx or 10.05.xxxx)Affected if Unable to retrieve firmware version from the device
-
Compare the firmware version against affected rangesCompare your installed version number to these ranges: 10.04.0000 to 10.04.3069, 10.05.0000 to 10.05.0069, 10.06.0000 to 10.06.0110, 10.07.0000 to 10.07.0001. Any version within these ranges is affected.Affected if The installed version falls within any of the affected ranges listed in the CVE (10.04.xxxx < 10.04.3070, 10.05.xxxx < 10.05.0070, 10.06.xxxx <= 10.06.0110, or 10.07.xxxx <= 10.07.0001)
-
Verify authentication requirements for the vulnerabilityThis CVE requires authenticated access to exploit. Check whether external or unauthorized user accounts have access to the switch management interfaces (SSH, Web UI, REST API)Affected if Unauthenticated or unauthorized users can access management interfaces - combined with an affected firmware version, this increases exposure
You are affected if your Aruba AOS-CX switch runs firmware version 10.04.3070 or lower, 10.05.0070 or lower, 10.06.0110 or lower, or 10.07.0001 or lower.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data10.04.307010.05.0070
Upgrade Aruba AOS-CX firmware to version 10.04.3070, 10.05.0070, 10.06.0110, or 10.07.0001 (or later) depending on the current firmware branch.
