Lenovo : Security Vulnerabilities, CVEs, Published In 2017

System boot process is not adequately secured In Lenovo E95 and ThinkCentre M710s/M710t because systems were shipped from factory without completing BIOS/UEFI initialization process.

Privilege escalation vulnerability in LXCA versions earlier than 1.3.2 where an authenticated user may be able to abuse certain web interface functionality to execute privileged commands within the underlying LXCA operating system.

A vulnerability was identified in Lenovo XClarity Administrator (LXCA) before 1.4.0 where LXCA user account names may be exposed to unauthenticated users with access to the LXCA web user interface. No password information of the user accounts is exposed.

An attacker who obtains access to the location where the LXCA file system is stored may be able to access credentials of local LXCA accounts in LXCA versions earlier than 1.3.2.

The Lenovo Service Framework Android application executes some system commands without proper sanitization of external input. In certain cases, this could lead to command injection which, in turn, could lead to remote code execution.

The Lenovo Service Framework Android application uses a set of nonsecure credentials when performing integrity verification of downloaded applications and/or data. This exposes the application to man-in-the-middle attacks leading to possible remote code execution.

The Lenovo Service Framework Android application accepts some responses from the server without proper validation. This exposes the application to man-in-the-middle attacks leading to possible remote code execution.

Improper access controls on several Android components in the Lenovo Service Framework application can be exploited to enable remote code execution.

A privilege escalation vulnerability was identified in Lenovo Active Protection System for ThinkPad systems versions earlier than 1.82.0.17. An attacker with local privileges could execute code with administrative privileges via an unquoted service path.

Some Lenovo brand notebook systems do not have write protections properly configured in the system BIOS. This could enable an attacker with physical or administrative access to a system to be able to flash the BIOS with an arbitrary image and potentially run malicious BIOS code.

A vulnerability has been identified in some Lenovo products that use UEFI (BIOS) code developed by American Megatrends, Inc. (AMI). With this vulnerability, conditions exist where an attacker with administrative privileges or physical access to a system may be able to run specially crafted code that can allow them to bypass system protections such as Device Guard and Hyper-V.

An industry-wide vulnerability has been identified in the implementation of the Open Shortest Path First (OSPF) routing protocol used on some Lenovo switches. Exploitation of these implementation flaws may result in attackers being able to erase or alter the routing tables of one or many routers, switches, or other devices that support OSPF within a routing domain.

An unquoted service path vulnerability was identified in the driver for the ThinkPad Compact USB Keyboard with TrackPoint versions earlier than 1.5.5.0. This could allow an attacker with local privileges to execute code with administrative privileges.

Privilege escalation vulnerability in Lenovo Nerve Center for Windows 10 on Desktop systems (Lenovo Nerve Center for notebook systems is not affected) that could allow an attacker with local privileges on a system to alter registry keys.

ThinkPad USB 3.0 Ethernet Adapter (part number 4X90E51405) driver, various versions, was found to contain a privilege escalation vulnerability that could allow a local user to execute arbitrary code with administrative or system level privileges.

In Lenovo XClarity Administrator (LXCA) before 1.3.0, if service data is downloaded from LXCA, a non-administrative user may have access to password information for users that have previously authenticated to the LXCA's internal LDAP server, including administrative accounts and service accounts with administrative privileges. This is an issue only for users who have used local authentication with LXCA and not remote authentication against external LDAP or ADFS servers.

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.

In Lenovo Connect2 versions earlier than 4.2.5.4885 for Windows and 4.2.5.3071 for Android, when an ad-hoc connection is made between two systems for the purpose of sharing files, the password for this ad-hoc connection will be stored in a user-readable location. An attacker with read access to the user's contents could connect to the Connect2 hotspot and see the contents of files while they are being transferred between the two systems.

In the Lenovo Power Management driver before 1.67.12.24, a local user may alter the trackpoint's firmware and stop the trackpoint from functioning correctly. This issue only affects ThinkPad X1 Carbon 5th generation.

In Lenovo Active Protection System before 1.82.0.14, an attacker with local privileges could send commands to the system's embedded controller, which could cause a denial of service attack on the system or the ability to alter hardware functionality.

Remote code execution in Lenovo Updates (not Lenovo System Update) allows man-in-the-middle attackers to execute arbitrary code.

Reset to default settings may occur in Lenovo ThinkServer TSM RD350, RD450, RD550, RD650, TD350 during a prolonged broadcast storm in TSM versions earlier than 3.77.

Privilege escalation in Lenovo Customer Care Software Development Kit (CCSDK) versions earlier than 2.0.16.3 allows local users to execute code with elevated privileges.

Log files generated by Lenovo XClarity Administrator (LXCA) versions earlier than 1.2.2 may contain user credentials in a non-secure, clear text form that could be viewed by a non-privileged user.
