LenovoCVEs & Vulnerabilities

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.

If multiple users are concurrently logged into a single system where one user is sending a command via the Lenovo ToolsCenter Advanced Settings Utility (ASU), UpdateXpress System Pack Installer (UXSPI) or Dynamic System Analysis (DSA) to a second machine, the other users may be able to see the user ID and clear text password that were used to access the second machine during the time the command is processing.

Privilege Escalation in Lenovo XClarity Administrator earlier than 1.2.0, if LXCA is used to manage rack switches or chassis with embedded input/output modules (IOMs), certain log files viewable by authenticated users may contain passwords for internal administrative LXCA accounts with temporary passwords that are used internally by LXCA code.

A Denial of Service in Intel Ethernet Controller's X710/XL710 with Non-Volatile Memory Images before version 5.05 allows a remote attacker to stop the controller from processing network traffic working under certain network use conditions.

A vulnerability has been identified in a signed kernel driver for the BIOS of some ThinkPad systems that can allow an attacker with Windows administrator-level privileges to call System Management Mode (SMM) services. This could lead to a denial of service attack or allow certain BIOS variables or settings to be altered (such as boot sequence). The setting or changing of BIOS passwords is not affected by this vulnerability.

A vulnerability has been identified in some Lenovo Notebook and ThinkServer systems where an attacker with administrative privileges on a system could install a program that circumvents Intel Management Engine (ME) protections. This could result in a denial of service or privilege escalation attack on the system.

During an internal security review, Lenovo identified a local privilege escalation vulnerability in Lenovo System Interface Foundation software installed on some Windows 10 PCs where a user with local privileges could run arbitrary code with administrator level privileges.
