Scenаriо:A clоud-bаsed dоcument mаnagement system allows users to upload files (e.g., PDFs, Word documents) for storage and sharing. However, a security audit discovered that the system did not properly validate the type of uploaded files, allowing attackers to upload executable scripts (e.g., .php, .exe) which could then be accessed and executed from the server.
