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 checksWork through these to decide whether this CVE applies to you.
-
Identify Telerik UI for AJAX installationSearch the application codebase, bin directories, and NuGet packages for Telerik.Web.UI.dll or similar Telerik UI for AJAX assembliesAffected if The Telerik UI for AJAX library is present in the application
-
Determine installed versionInspect the Telerik assembly metadata (right-click the DLL in Windows Explorer, view Properties > Details, or use a .NET disassembler tool) to find the FileVersion or AssemblyVersionAffected if The version number falls within the range 2011.2.712 through 2025.1.218 (inclusive)
-
Verify application uses Telerik AJAX controlsSearch source code for Telerik.Web.UI namespace references or Telerik AJAX control declarations in ASPX/ASCX filesAffected if The application implements Telerik AJAX components that could accept user-supplied input triggering reflection operations
If Telerik UI for AJAX version 2011.2.712 or higher through 2025.1.218 or lower is installed and the application uses Telerik AJAX controls that handle user input, the environment is likely affected by this unsafe reflection vulnerability.
