IBM System X3750 M4

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.

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.

An unprivileged attacker with connectivity to the IMM2 could cause a denial of service attack on the IMM2 (Versions earlier than 4.4 for Lenovo System x and earlier than 6.4 for IBM System x). Flooding the IMM2 with a high volume of authentication failures via the Common Information Model (CIM) used by LXCA and OneCLI and other tools can exhaust available system memory which can cause the IMM2 to reboot itself until the requests cease.

In various firmware versions of Lenovo System x, the integrated management module II (IMM2)'s first failure data capture (FFDC) includes the web server's private key in the generated log file for support.

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.

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.

Missing System x Flash Memory Write Protection Lock Bit

Integrated Management Module (IMM) 2 1.00 through 2.00 on IBM System X and Flex System servers supports SSL cipher suites with short keys, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack against (1) SSL or (2) TLS traffic.

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.
