### Introduction 

`angular-base64-upload` versions prior to v0.1.21 are vulnerable to unauthenticated remote code execution via the `angular-base64-upload/demo/server.php` endpoint. Exploiting this vulnerability allows an attacker to upload arbitrary file content to the server, which can subsequently be accessed through the angular-base64-upload/demo/uploads endpoint. This lead to the execution of previously uploaded content and ultimately enable the attacker to achieve code execution on the server.
