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
A vulnerability exists that can be exploited by an authenticated client that is connected to the same network segment as the CoreTec 4, having any level of access VIEWER to ADMIN. To exploit the vulnerability the attacker can inject shell commands through a particular field of the web user interface that will be executed by the 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 confidence

Command injection vulnerability in CoreTec 4 web interface allows authenticated users (VIEWER to ADMIN) on the same network segment to inject and execute shell commands through a specific web UI field.

MitigationImplement strict input validation and sanitization on all web interface fields to prevent shell command injection; apply network segmentation to limit exposure to trusted users.

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 device model and firmware version
    Access the CoreTec 4 web interface, navigate to System Settings or About section, and record the firmware version displayed. Alternatively, check the device label or management interface for the firmware build number.
    Affected if The firmware version is below 3.0.1 (e.g., 3.0.0, 2.x.x, or any version prior to 3.0.1)
  2. Confirm the web interface is accessible
    Attempt to reach the CoreTec 4 web UI via HTTP/HTTPS on the expected management port (typically 443 or 8080) from a browser on the same network segment.
    Affected if The web interface responds and displays a login page or admin dashboard
  3. Verify authentication is enabled or configurable
    Check the user management or security settings within the web interface to confirm user accounts (VIEWER, OPERATOR, ADMIN roles) exist and authentication is required for access.
    Affected if User accounts with roles from VIEWER to ADMIN are present and authentication is required to access the web interface
  4. Confirm network accessibility to the web interface
    Use network scanning tools (nmap, netstat) or check firewall rules to determine if the web management port is listening on interfaces accessible from network segments beyond the trusted management network.
    Affected if The web interface port is bound to a non-loopback interface and is reachable from network segments beyond direct administrative access

You are affected if the Abb Txpert Hub CoreTec 4 device is running firmware version prior to 3.0.1 and the web interface is accessible from your network with authentication enabled.

Upgrade available Upgrade to 3.0.1 or later
Fixed in 3.0.1
Interim mitigation

Implement strict input validation and sanitization on all web interface fields to prevent shell command injection; apply network segmentation to limit exposure to trusted users.

Recommended fix Moderate confidence

Firmware version 3.0.1

  1. Verify current firmware version through the Txpert Hub web interface or CLI
  2. Download firmware version 3.0.1 or later from the official ABB support portal (search.abb.com)
  3. Review ABB upgrade documentation for Txpert Hub Coretec 4 before proceeding
  4. Upload the firmware file through the web-based administration interface
  5. Confirm the upgrade completes successfully and the system reboots
  6. Verify the new firmware version is 3.0.1 or later
  7. Test that the web interface functionality remains operational
