Dell iDRAC6 Improper Authentication (CVE-2013-4783)

critical Tenable OT Security Plugin ID 501892

Description

The Dell iDRAC6 with firmware 1.x before 1.92 and 2.x and 3.x before 3.42, and iDRAC7 with firmware before 1.23.23, allows remote attackers to bypass authentication and execute arbitrary IPMI commands by using cipher suite 0 (aka cipher zero) and an arbitrary password. NOTE: the vendor disputes the significance of this issue, stating DRAC's are intended to be on a separate management network; they are not designed nor intended to be placed on or connected to the Internet.
