Description

Dell iDRAC6 contains a flaw related to the Intelligent Platform Management Interface (IPMI) implementation. The issue is due to the vendor shipping their devices with the cipher suite '0' (aka 'cipher zero') enabled. This allows a remote attacker to authenticate to the IPMI interface using an arbitrary password. The only information required is a valid account, but most vendors ship with a default 'admin' account. This would allow an attacker to have full control over the IPMI functionality, including machines that may be powered down.

Classification

Location: Remote / Network Access
Attack Type: Authentication Management
Impact: Loss of Integrity
Solution: Workaround
Exploit: Exploit Public

Solution

Immediately after installation, change all default installed accounts to use a unique and secure password. When possible, change default account names to custom names as well.
