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 authenticated command injection vulnerability in Weintek cMT2078X easyweb Web Version v2.1.3, OS v20220215 allows attackers to execute arbitrary code or access sensitive information via injecting a crafted payload into the HMI Name parameter.

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

Authenticated command injection vulnerability in Weintek cMT2078X HMI web interface (easyweb v2.1.3) allows attackers with valid credentials to inject arbitrary commands through the HMI Name parameter, achieving code execution or accessing sensitive information.

MitigationUpdate to vendor-supplied patched firmware version; if unavailable, disable the easyweb interface or isolate the device on a restricted network segment, and rotate credentials immediately.

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 cMT2078X firmware version
    Access the HMI web interface and navigate to System Information/System Settings page, or access the device directly through its built-in display to check the firmware version in the system settings menu. The exact path varies by firmware but is typically found under Settings > System Info or similar.
    Affected if The installed firmware version is exactly 2.1.3
  2. Verify easyweb interface is enabled
    Check the HMI configuration or system settings to confirm whether the easyweb web server service is turned on. This is typically found in the Network settings or System Services configuration area of the HMI interface.
    Affected if The easyweb web interface service is enabled and running
  3. Confirm web interface is network-accessible
    Determine if the HMI web interface (typically on port 80/443) is exposed to the network. Check firewall rules, VLAN configuration, or network segmentation to see if the web interface can be reached from any network segment beyond the HMI itself.
    Affected if The easyweb interface is reachable from a network beyond the local HMI display

You are affected if your cMT2078X runs firmware version 2.1.3, the easyweb web interface is enabled, and it is accessible over the network where attackers could use stolen credentials to inject commands through the HMI Name parameter.
