Command Execution vulnerability in Simplicity Installer

Vulnerable endpoints accept user-controlled input through a URL in JSON format which enables command execution. The commands allowed to execute can open executables. However, the commands cannot pass parameters or arguments.  To successfully execute this attack, the attacker needs to be on the same network.
