Official description
HortusFox-Web prior to version 6.1 contains a remote code execution vulnerability that allows authenticated administrators to execute arbitrary OS commands as the web server user by abusing the Import/Export functionality. Attackers can leverage the Import/Export feature, which is intended solely for data portability, to deploy and execute malicious code on the underlying application server host.

The underlying weakness: Unrestricted Upload of File with Dangerous Type
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
How developers prevent this class of flaw
- Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
