Vulnerability Details:

CVE ID: CVE-2014-0860

Description:The administrative IPMI credentials for authenticating communications between the AMM and IMM – they are stored in plaintext within the firmware binaries. Using these credentials, any user with access to a blade’s IMM management interface (either via the chassis internal network or in-band through the IMM’s Ethernet over USB interface) can send it arbitrary IPMI commands. This includes the ability to create new IMM management accounts with supervisor privileges which could then be used to connect to the blade’s remote console facility.
