The Intelligent Platform Management Interface (IPMI) implementation in Integrated Management Module (IMM) and Integrated Management Module II (IMM2) on IBM BladeCenter, Flex System, System x iDataPlex, and System x3### servers has a default password for the IPMI user account, which makes it easier for remote attackers to perform power-on, power-off, or reboot actions, or add or modify accounts, via unspecified vectors.
