IBM Integrated Management Module IPMI weak passwords

imm-cve20134037-ipmi-weak (86173) The risk level is classified as MediumMedium Risk

Description:

The Integrated Management Module (IMM) and Integrated Management Module II (IMM2) used by multiple IBM servers have multiple errors in the RAKP protocol, which is specified by the IPMI standard for authentication. Although the IMMs do not allow the use of null passwords, an attacker could reverse engineer the RAKP transactions to determine a password. The authentication process for IPMI requires the management controller to send a hash of the requested user's password to the client, prior to the client authenticating. This process is a key part of the IPMI specification. The password hash can broken using an offline brute force or dictionary attack.

*CVSS:
