Then all hosts in same network will be in risk. Sometime the layer two of the OSI has a security issues especially In the DMZ environment because of DMZ only protect layer three only filer incoming and outgoing traffic. In addition, in case using firewall to protect the layer two and the Firewall cannot filter local traffics inside a VLAN; the local traffic in one subnet does not go through upper level or firewall.
