A stored cross-site scripting (XSS) vulnerability exists in various firmware versions of the legacy IBM System x IMM (IMM v1) embedded Baseboard Management Controller (BMC). This vulnerability could allow an unauthenticated user to cause JavaScript code to be stored in the IMM log which may then be executed in the user's web browser when IMM log records containing the JavaScript code are viewed. The JavaScript code is not executed on IMM itself. The later IMM2 (IMM v2) is not affected.

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.

The RAKP protocol support in 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 sends a password hash to the client, which makes it easier for remote attackers to obtain access via a brute-force attack.

The Intelligent Platform Management Interface (IPMI) implementation in Integrated Management Module (IMM) on IBM BladeCenter, Flex System, System x iDataPlex, and System x3### servers uses cleartext for password storage, which allows context-dependent attackers to obtain sensitive information by reading a file.
