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 local code execution vulnerability is possible in Telerik UI for WinForms beginning in v2021.1.122 but prior to v2024.2.514. This vulnerability could allow an untrusted theme assembly to execute arbitrary code on the local Windows 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 · moderate confidence

A local code execution vulnerability in Telerik UI for WinForms allows untrusted theme assemblies to execute arbitrary code on the local Windows system. This affects versions v2021.1.122 through v2024.2.513. The vulnerability stems from insecure loading of theme assemblies that can contain malicious code.

MitigationUpgrade Telerik UI for WinForms to v2024.2.514 or later, and audit all theme assembly sources to ensure only trusted, verified assemblies are used in production.

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 Telerik UI for WinForms installation
    Search for Telerik.WinControls.UI.dll or similar Telerik WinForms assemblies in the application's bin directory or installed components.
    Affected if Telerik UI for WinForms assemblies are present in the application environment.
  2. Determine the installed Telerik UI for WinForms version
    Right-click the Telerik.WinControls.UI.dll assembly, select Properties, and check the File Version attribute, or inspect the assembly metadata using a tool like dotPeek or ILSpy.
    Affected if The reported version falls within the range v2021.1.122 through v2024.2.513.
  3. Identify theme assembly configuration
    Examine the application configuration files (App.config, web.config) and any custom theme loading code to determine if custom or third-party theme assemblies are being loaded at runtime.
    Affected if The application loads theme assemblies from untrusted or external sources.
  4. Review theme assembly sources
    Inspect the application's theme folder or deployment directory for any .dll files that are not part of the official Telerik installation package.
    Affected if Non-official or externally-sourced theme assemblies are present in the application deployment.

The environment is affected if Telerik UI for WinForms version 2021.1.122 through 2024.2.513 is installed and the application loads theme assemblies, particularly from untrusted or external sources.
