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 OS command injection vulnerability exists in XWEB Pro version 1.12.1 and prior, enabling an authenticated attacker to achieve remote code execution on the system by configuring a maliciously crafted LCD state which is later processed during system setup, enabling remote code execution.

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

An OS command injection vulnerability in XWEB Pro version 1.12.1 and prior allows authenticated attackers to achieve remote code execution by submitting a maliciously crafted LCD state configuration that gets processed during system setup without proper input sanitization.

MitigationImplement strict input validation and sanitization on the LCD state parameter before passing it to system commands, and apply the principle of least privilege to the user account used for setup operations.

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 installed XWEB Pro firmware version
    Access the device web interface or check system information page for the firmware version number. Common paths include /status, /about, or the main dashboard showing system details.
    Affected if The displayed version is 1.12.1 or any version number lower than 1.12.1 (e.g., 1.12.0, 1.11.x, 1.10.x).
  2. Locate the LCD state configuration setting
    Navigate to the system setup or configuration section of the XWEB Pro web interface. Look for LCD-related settings, display configuration, or state parameters under the setup or initialization screens.
    Affected if The LCD state configuration option exists in the interface and is accessible within the setup workflow.
  3. Verify authenticated access to setup functionality
    Log into the XWEB Pro device with valid credentials and confirm whether the setup or configuration pages remain accessible after initial setup completion.
    Affected if An authenticated user can access the system setup or configuration features where the LCD state parameter is processed.
  4. Check for input validation on configuration parameters
    Inspect any LCD state or similar configuration parameters submitted during setup. Determine if the interface accepts special characters or command operators in these fields.
    Affected if The application accepts and processes raw input without apparent sanitization of shell metacharacters in the LCD state configuration field.

You are affected if your Copeland XWEB Pro device runs firmware version 1.12.1 or lower AND the LCD state configuration feature is accessible to authenticated users without proper input sanitization in place.

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 data
Upgrade available Upgrade to a release after 1.12.1
Interim mitigation

Implement strict input validation and sanitization on the LCD state parameter before passing it to system commands, and apply the principle of least privilege to the user account used for setup operations.
