How to fix?

There is no fixed version for UmbracoForms.

Overview

UmbracoForms is a tool that makes creating contact forms, entry forms and questionnaires just as easy as using Word.

Affected versions of this package are vulnerable to Insecure Defaults. When using the default configuration for upload forms, it is possible to upload arbitrary file types.

The package offers a way for users to mitigate the issue. The users of this package can create a custom workflow and frontend validation that blocks certain file types, depending on their security needs and policies.

PoC by Adrian Gigliotti

  1. Submit a malicious file through a file upload form created using UmbracoForms with default configuration.
  2. In the administrator's view, you can verify that the file has been stored and is available for interaction.
