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 issue in NCR Terminal Handler v.1.5.1 allows a remote attacker to execute arbitrary code and obtain sensitive information via a crafted POST request to the UserService component

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 confidence

NCR Terminal Handler v1.5.1 contains a critical vulnerability in the UserService component that allows remote attackers to execute arbitrary code and obtain sensitive information via crafted POST requests. The vulnerability is exploitable over the network without authentication, which aligns with the critical CVSS score.

MitigationApply vendor patch or upgrade to a fixed version of NCR Terminal Handler. If immediate patching is not possible, restrict network access to the UserService component and implement network segmentation to limit exposure.

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 if NCR Terminal Handler is installed
    Locate the NCR Terminal Handler application on the system. Check for its process, service, or installation directory. Common locations may include /opt/, /usr/local/, or Windows program files.
    Affected if NCR Terminal Handler is present on the system
  2. Verify the installed version is 1.5.1
    Check the version of NCR Terminal Handler by examining its executable, service properties, or version file. Use commands like 'ls -la' on the binary, check the application manifest, or query the service with 'systemctl status' or 'sc query' depending on the OS.
    Affected if The version is exactly 1.5.1
  3. Confirm UserService component is exposed
    Identify if the UserService component is running and listening on a network port. Check configuration files for UserService endpoint definitions, and use 'netstat -an' or 'ss -tuln' to identify listening ports associated with NCR Terminal Handler.
    Affected if UserService is running and bound to a network interface accessible to attackers
  4. Check if UserService accepts unauthenticated POST requests
    Review the UserService configuration and access controls. Examine whether authentication is required for the POST endpoints. This may require reviewing configuration files or testing the endpoint with a crafted request in an isolated test environment.
    Affected if UserService accepts POST requests without authentication

You are affected if NCR Terminal Handler version 1.5.1 is installed AND the UserService component is exposed on the network without authentication controls.
