The vulnerabilities are in the Intelligent Platform Management Interface (IPMI) protocol specification that describes how BMCs communicate locally and across networks. The issues range from the ability to bypass authentication mechanisms, steal password hashes that can be brute-forced offline, to UPnP-based vulnerabilities that cannot be disabled and could lead to remote root compromises.
Dan Farmer, creator of the SATAN vulnerability scanner, discovered the vulnerabilities while conducting research under a DARPA Cyber Fast Track grant that was completed in January. Metasploit creator and Rapid7 CSO HD Moore then collaborated with Farmer by conducting an Internet-wide scan of the IPMI protocol to discover the breadth of the issue."
