MapDrv (C:\Program Files\Lenovo\System Update\mapdrv.exe) In Lenovo System Update versions earlier than 5.07.0072 contains a local vulnerability where an attacker entering very large user ID or password can overrun the program's buffer, causing undefined behaviors, such as execution of arbitrary code. No additional privilege is granted to the attacker beyond what is already possessed to run MapDrv.Show less

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.Show less

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.Show less

Sensitive data stored by Lenovo Fingerprint Manager Pro, version 8.01.86 and earlier, including users' Windows logon credentials and fingerprint data, is encrypted using a weak algorithm, contains a hard-coded password, and is accessible to all users with local non-administrative access to the system in which it is installed.Show less

In Enterprise Networking Operating System (ENOS) in Lenovo and IBM RackSwitch and BladeCenter products, an authentication bypass known as "HP Backdoor" was discovered during a Lenovo security audit in the serial console, Telnet, SSH, and Web interfaces. This bypass mechanism can be accessed when performing local authentication under specific circumstances. If exploited, admin-level access to the switch is granted.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less
