The TPM on Integrated Management Module II (IMM2) on IBM Flex System x222 servers with firmware 1.00 through 3.56 allows remote attackers to obtain sensitive key information or cause a denial of service by leveraging an incorrect configuration. IBM X-Force ID: 91146.

Integrated Management Module II (IMM2) on IBM Flex System, NeXtScale, System x3xxx, and System x iDataPlex systems might allow remote authenticated users to obtain sensitive account information via vectors related to generated Service Advisor data (FFDC). IBM X-Force ID: 91149.

In the IMM2 firmware of Lenovo System x servers, remote commands issued by LXCA or other utilities may be captured in the First Failure Data Capture (FFDC) service log if the service log is generated when that remote command is running. Captured command data may contain clear text login information. Authorized users that can capture and export FFDC service log data may have access to these remote commands.

The firmware before 3.66E in IBM BladeCenter Advanced Management Module (AMM), the firmware before 1.43 in IBM Integrated Management Module (IMM), and the firmware before 4.15 in IBM Integrated Management Module II (IMM2) contains cleartext IPMI credentials, which allows attackers to execute arbitrary IPMI commands, and consequently establish a blade remote-control session, by leveraging access to (1) the chassis internal network or (2) the Ethernet-over-USB interface.
