New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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."
