Iomega and LenovoEMC NAS Web UI Vulnerabilities

For some Iomega, Lenovo, LenovoEMC NAS devices versions 4.1.402.34662 and earlier, when joining a PersonalCloud setup, an attacker can craft a command injection payload using backtick "``" characters in the client:password parameter. As a result, arbitrary commands may be executed as the root user. The attack requires a value __c and iomega parameter.

Iomega and LenovoEMC NAS Web UI Vulnerabilities

For some Iomega, Lenovo, LenovoEMC NAS devices versions 4.1.402.34662 and earlier, the file upload functionality of the Content Explorer application is vulnerable to path traversal. As a result, users can upload files anywhere on the device's operating system as the root user.

CMM Security Vulnerability

Lenovo Chassis Management Module (CMM) prior to version 2.0.0 utilizes a hardcoded encryption key to protect certain secrets. Possession of the key can allow an attacker that has already compromised the server to decrypt these secrets.

LXCI for VMware

In versions prior to 5.5, LXCI for VMware allows an authenticated user to download any system file due to insufficient input sanitization during file downloads.

CMM Security Vulnerability

Lenovo Chassis Management Module (CMM) prior to version 2.0.0 allows unauthenticated users to retrieve information related to the current authentication configuration settings. Exposed settings relate to password lengths, expiration, and lockout configuration.

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.

BIOS Write Protection Race Condition

In some Lenovo IdeaPad consumer notebook models, a race condition in the BIOS flash device locking mechanism is not adequately protected against, potentially allowing an attacker with administrator access to alter the contents of BIOS.

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.

The Lenovo Help Android app versions earlier than 6.1.2.0327 had insufficient access control for some functions which, if exploited, could have led to exposure of approximately 400 email addresses and 8,500 IMEI.

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.

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.

In Lenovo xClarity Administrator versions earlier than 2.1.0, an authenticated LXCA user may abuse a web API debug call to retrieve the credentials for the System Manager user.

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.

BIOS Modules Unprotected by Intel Boot Guard Vulnerable to Physical Attack

In some Lenovo ThinkPad products, one BIOS region is not properly included in the checks, allowing injection of arbitrary code.

In some Lenovo ThinkPads, an unquoted search path vulnerability was found in various versions of the Synaptics Pointing Device driver which could allow unauthorized code execution as a low privilege user.

LXCI for VMware and LXCI for Microsoft System Center

LXCI for VMware versions prior to 5.5 and LXCI for Microsoft System Center versions prior to 3.5, allow an authenticated user to write to any system file due to insufficient sanitization during the upload of a certificate.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, the SMM web interface for changing Enclosure VPD fails to sufficiently sanitize all input for HTML tags, possibly opening a path for cross-site scripting.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, the SMM records hashed passwords to a debug log when user authentication fails.

System Management Module Vulnerabilities

In System Management Module (SMM) versions prior to 1.06, an internal SMM function that retrieves configuration settings is prone to a buffer overflow.

LXCI for VMware

In versions prior to 5.5, LXCI for VMware allows an authenticated user to write to any system file due to insufficient sanitization during the upload of a backup file.
