The IMM2 First Failure Data Capture function collects management module logs and diagnostic information when a hardware error is detected. This information is made available for download through an SFTP server hosted on the IMM2 management network interface. In versions earlier than 4.90 for Lenovo System x and earlier than 6.80 for IBM System x, the credentials to access the SFTP server are hard-coded and described in the IMM2 documentation, allowing an attacker with management network access to obtain the collected FFDC data. After applying the update, the IMM2 will create random SFTP credentials for use with OneCLI.

Some Lenovo System x server BIOS/UEFI versions, when Secure Boot mode is enabled by a system administrator, do not properly authenticate signed code before booting it. As a result, an attacker with physical access to the system could boot unsigned code.

A stack overflow vulnerability was discovered within the web administration service in Integrated Management Module 2 (IMM2) earlier than version 4.70 used in some Lenovo servers and earlier than version 6.60 used in some IBM servers. An attacker providing a crafted user ID and password combination can cause a portion of the authentication routine to overflow its stack, resulting in stack corruption.

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.
