Zeroshell is a small open-source Linux distribution for servers and embedded systems which aims to provide network services.

[1][2] Its administration relies on a web-based graphical interface; no shell is needed to administer and configure it.

Zeroshell is available as Live CD and CompactFlash images, and VMware virtual machines.

Zeroshell can be installed on any IA-32 computer with almost any Ethernet interface.

[4] There are several known vulnerabilities for various versions of this software: V2, V3.6x up to V3.7, V3.9.0, V3.9.3 and last V3.9.5 for example,[5] allowing an attacker to e.g. gain root access to the device easily.
