Vulnerabilidades

A potential vulnerability in the SMI callback function used in the legacy BIOS mode USB drivers in some legacy Lenovo and IBM System x servers may allow arbitrary code execution. Servers operating in UEFI mode are not affected.

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.

A write protection lock bit was left unset after boot on an older generation of Lenovo and IBM System x servers, potentially allowing an attacker with administrator access to modify the subset of flash memory containing Intel Server Platform Services (SPS) and the system Flash Descriptors.

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…

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…

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.
