Dell Best Practices regarding iDRAC:

In addition to maintaining up to date iDRAC firmware, Dell also advises the following:

• iDRACs are not designed nor intended to be placed on or connected to the Internet; they are intended to be on a separate management network. Placing or connecting iDRACs directly to the Internet could expose the connected system to security and other risks for which Dell is not responsible.   
• Along with locating iDRACs on a separate management subnet, users should isolate the management subnet/vLAN with technologies such as firewalls, and limit access to the subnet/vLAN to authorized server administrators.
• Dell Technologies recommends that customers consider any deployment factors that may be relevant to their environment to assess their overall risk.

Link to remedies:

Customers can download iDRAC firmware for PowerEdge servers. For all other platforms, select the platform from the Dell support site.
