In Lenovo xClarity Administrator versions earlier than 2.1.0, an authenticated LXCA user can, under specific circumstances, inject additional parameters into a specific web API call which can result in privileged command execution within LXCA's underlying operating system.Show less

In Lenovo xClarity Administrator versions earlier than 2.1.0, an attacker that gains access to the underlying LXCA file system user may be able to retrieve a credential store containing the service processor user names and passwords for servers previously managed by that LXCA instance, and potentially decrypt those credentials more easily than intended.Show less

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.Show less

For the Lenovo Smart Assistant Android app versions earlier than 12.1.82, an attacker with physical access to the smart speaker can, by pressing a specific button sequence, enter factory test mode and enable a web service intended for testing the device. As with most test modes, this provides extra privileges, including changing settings and running code. Lenovo Smart Assistant is an Amazon Alexa-enabled smart speaker developed by Lenovo.Show less

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
