Technical details
UnoPim (up to version 0.2.0) contains an unrestricted file upload vulnerability in the user creation endpoint (/admin/settings/users/create). The application only performs client-side validation for file types, allowing an attacker to intercept the request and upload a PHP shell by modifying the file extension and content-type. Once uploaded, the file is stored in a web-accessible directory, enabling the attacker to execute arbitrary system commands or establish a reverse shell. This vulnerability is mitigated by the requirement for high privileges (dashboard access), but it allows for full server compromise. A fix is available in version 0.2.1.
