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
File Manager in Syncfusion Essential Studio for ASP.NET MVC before 27.1.55 has a traversal issue that is related to the request parameter, aka I644734.

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

The File Manager component in Syncfusion Essential Studio for ASP.NET MVC versions prior to 27.1.58 contains a path traversal vulnerability. The issue allows attackers to manipulate the request parameter to access files outside the intended directory by using '../' sequences in the file path, potentially exposing sensitive system files.

MitigationUpgrade to Syncfusion Essential Studio for ASP.NET MVC version 27.1.55 or later. As an interim measure, implement strict input validation on all file path parameters to reject sequences containing '../' and ensure file operations are restricted to allowed directory boundaries.

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. Locate Syncfusion assemblies in the application
    Search the application's bin directory and referenced DLLs for Syncfusion.EJ.MVC.dll or similar Syncfusion assemblies. Use file explorer or a command like 'dir /s /b Syncfusion*.dll' at the application root.
    Affected if Syncfusion assemblies are found in the application
  2. Determine the installed Syncfusion version
    Right-click the Syncfusion assembly DLL, select Properties, and check the Version field in the Details tab. Alternatively, examine the packages.config file or .csproj file for the Syncfusion.EJ.MVC package version.
    Affected if The version shown is earlier than 27.1.58
  3. Verify the File Manager component is in use
    Search the codebase for 'FileManager' in view files (.cshtml), controllers, or routes configuration. Look for references to 'Syncfusion.EJ.Mvc.FileManager' or similar FileManager-related code.
    Affected if File Manager component code or configuration is present in the application
  4. Confirm the vulnerability is exploitable
    Examine the application's request handling for file operations. Check if the File Manager accepts file path parameters that could contain '../' sequences. Review the controller actions handling file requests.
    Affected if File Manager accepts user-supplied path parameters without validation rejecting '../' sequences

The environment is affected if Syncfusion Essential Studio for ASP.NET MVC with a version prior to 27.1.58 is installed and the File Manager component is in use with path parameters that accept unvalidated input.

Mitigation

Upgrade to Syncfusion Essential Studio for ASP.NET MVC version 27.1.55 or later. As an interim measure, implement strict input validation on all file path parameters to reject sequences containing '../' and ensure file operations are restricted to allowed directory boundaries.

Recommended fix High confidence

27.1.55 or later

  1. Identify the current version of Syncfusion Essential Studio for ASP.NET MVC in use by checking the referenced assemblies or NuGet packages
  2. Download Syncfusion Essential Studio version 27.1.55 or later from the official Syncfusion website (ej2.syncfusion.com)
  3. Update the Syncfusion assemblies or NuGet packages in the project to version 27.1.55 or newer
  4. Rebuild and test the application, specifically verifying the File Manager component functions correctly
  5. Redeploy the updated application to production
Caveat Review the Syncfusion release notes for version 27.1.55 to check for any breaking changes that may affect the application
