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
SCM Software is a client and server application. An Authenticated System manager client can execute LINQ query in the SCM server, for customized filtering. An Authenticated malicious client can send a specially crafted code to skip the validation and execute arbitrary code (RCE) on the SCM Server remotely. Malicious clients can execute any command by using this RCE vulnerability.

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

This is an authenticated remote code execution vulnerability in SCM Software where an authenticated System manager client can bypass validation in the LINQ query filtering functionality to inject and execute arbitrary code on the SCM Server remotely.

MitigationImplement strict input validation and parameterized queries for LINQ operations, enforce proper authentication and authorization checks on all client requests, and apply network segmentation to limit System manager client access.

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 SCM Software installation and version
    Locate the SCM Software installation directory and check the version information (typically in a version file, about dialog, or executable properties). Compare your installed version against any officially documented affected versions for CVE-2024-0400.
    Affected if The installed SCM Software version falls within an affected version range and the System manager client feature is accessible.
  2. Verify System manager client access is enabled
    Check the SCM Server configuration settings or user role definitions to determine whether the System manager client functionality is enabled and accessible to any authenticated users.
    Affected if System manager client access is enabled and users with this role can connect to the SCM Server.
  3. Inspect LINQ query filtering configuration
    Review the SCM Server configuration files or settings related to LINQ query filtering to determine if the filtering functionality that lacks proper input validation is exposed and operational.
    Affected if The LINQ query filtering functionality is enabled and accessible to authenticated System manager clients.
  4. Check authentication enforcement on System manager interface
    Examine the authentication and authorization configuration for the System manager client interface to verify whether proper validation is enforced on incoming requests.
    Affected if The System manager interface relies on the vulnerable LINQ query filtering without sufficient input validation.

A user is affected if they run an SCM Software version within the affected range with the System manager client feature enabled and the vulnerable LINQ query filtering functionality exposed to authenticated users.
