CVE-2026-23816
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 vulnerability in the command line interface of AOS-CX Switches could allow an authenticated remote attacker to execute arbitrary commands on the underlying operating system.
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 command injection vulnerability in the AOS-CX Switch CLI allows authenticated remote attackers to execute arbitrary OS commands. An attacker with valid CLI credentials can inject OS-level commands through the interface, potentially compromising the switch's underlying Linux-based operating system.

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.
-
Confirm AOS-CX switch modelRun 'show system information' or check the switch serial label to verify the device is an AOS-CX switchAffected if The device is not an AOS-CX switch (this CVE does not apply)
-
Identify firmware versionExecute 'show version' in the CLI to retrieve the installed firmware versionAffected if Unable to retrieve version or version is not the latest vendor-recommended release for AOS-CX
-
Verify CLI access is enabledRun 'show ip ssh' or 'show telnet' to check if SSH or Telnet access to the CLI is enabledAffected if SSH or Telnet access is enabled and exposed to network (creates attack vector)
-
Check remote access configurationRun 'show running-config | include ip ssh' or review management interface configuration to see if CLI is accessible from non-local networksAffected if CLI is reachable from untrusted networks or management VLAN is not properly isolated
-
Review admin accountsRun 'show users' or 'show aaa authentication' to see authenticated CLI users and authentication method in useAffected if Weak authentication is configured or shared credentials exist (enables the authenticated attack vector)
The environment is affected if it runs an AOS-CX switch with CLI access enabled and a firmware version that has not been patched per vendor guidance, particularly if the CLI is reachable from network segments beyond trusted administration IPs.

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 dataApply the vendor-supplied firmware update for AOS-CX switches. If a patch is unavailable, restrict CLI access to trusted administrative IPs only and enforce strong authentication credentials.
