CVE-2024-9137
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 · uneditedThe affected product lacks an authentication check when sending commands to the server via the Moxa service. This vulnerability allows an attacker to execute specified commands, potentially leading to unauthorized downloads or uploads of configuration files and system compromise.
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 confidenceMoxa service lacks authentication verification when processing commands sent to the server, enabling unauthenticated attackers to execute arbitrary commands. This allows unauthorized access to download/upload configuration files and potentially compromise the entire 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.
-
Identify Moxa software installationsSearch for Moxa-related processes and services: run 'tasklist /svc' on Windows or 'ps aux | grep -i moxa' on Linux. Also check installed programs for Moxa-related software.Affected if Moxa processes or services are found running on the system
-
Locate Moxa service configuration filesSearch for Moxa configuration directories: common paths include C:\Program Files\Moxa on Windows or /opt/moxa, /etc/moxa on Linux. Look for config files related to the service.Affected if Moxa configuration files exist and the service is configured to run
-
Check service network binding and exposureRun 'netstat -an | grep <port>' (where <port> is the Moxa service port, commonly 80, 443, or 48000) or use 'ss -tlnp' to see which interfaces the service is listening on. Verify if it binds to 0.0.0.0 or external IPs.Affected if The Moxa service is listening on a network interface accessible from untrusted networks
-
Inspect authentication configurationExamine Moxa service configuration files for authentication settings. Look for parameters like 'auth_enabled', 'require_authentication', or similar flags that control command authorization.Affected if Authentication is disabled, not enforced, or set to bypass for commands
-
Verify command processing accessIf possible, review the service logs or attempt a test command locally to see if the service processes commands without requiring credentials. Check for any token, key, or credential requirements in the service.Affected if The service accepts and processes commands without requiring any authentication token or credentials
A system is affected if it runs a Moxa service that processes commands without requiring authentication, particularly if the service is network-exposed.

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 dataImplement proper authentication checks for all commands sent to the Moxa service, enforce authorization before command execution, and restrict network exposure of the affected service to trusted endpoints only.
