descriptionThe remote host is running iDRAC7 or iDRAC8 with a firmware version prior to 2.61.60.60, or iDRAC9 with a firmware version prior to 3.20.21.20, 3.21.24.22, 3.21.26.22 or 3.23.23.23 and is therefore affected by the following vulnerabilities: - An elevation of privilege vulnerability exists in Redfish interface. An authenticated, attacker can exploit, via a permissions check flaw, to gain elevated privileges. (CVE-2018-15774) - A flaw exists in iDRAC7 / iDRAC8 due to improper handling of an error. A unauthenticated, remote attacker can exploit this to gain access to a u-boot shell. (CVE-2018-15776)
