Vulnerabilities (CVE)

A DLL search path vulnerability was reported in PaperDisplay Hotkey Service version 1.2.0.8 that could allow privilege escalation. Lenovo has ended support for PaperDisplay Hotkey software as the Night light feature introduced in Windows 10 Build 1703 provides similar features.

A denial of service vulnerability was reported in Lenovo System Update before version 5.07.0084 that could allow service log files to be written to non-standard locations.

An internal product security audit discovered a session handling vulnerability in the web interface of ThinkAgile CP-SB (Storage Block) BMC in firmware versions prior to 1908.M. This vulnerability allows session IDs to be reused, which could provide unauthorized access to the BMC under certain circumstances. This vulnerability does not affect ThinkSystem XCC, System x IMM2, or other BMCs.

A vulnerability in various versions of Iomega and LenovoEMC NAS products could allow an unauthenticated user to access files on NAS shares via the API.

A stored cross-site scripting (XSS) vulnerability exists in various firmware versions of the legacy IBM System x IMM (IMM v1) embedded Baseboard Management Controller (BMC). This vulnerability could allow an unauthenticated user to cause JavaScript code to be stored in the IMM log which may then be executed in the user's web browser when IMM log records containing the JavaScript code are viewed. The JavaScript code is not executed on IMM itself. The later IMM2 (IMM v2) is not affected.

An internal product security audit of Lenovo XClarity Administrator (LXCA) discovered HTTP proxy credentials being written to a log file in clear text. This only affects LXCA when HTTP proxy credentials have been configured. This affects LXCA versions 2.0.0 to 2.3.x.

In various firmware versions of Lenovo System x, the integrated management module II (IMM2)'s first failure data capture (FFDC) includes the web server's private key in the generated log file for support.

In Lenovo systems, SMM BIOS Write Protection is used to prevent writes to SPI Flash. While this provides sufficient protection, an additional layer of protection is provided by SPI Protected Range Registers (PRx). Lenovo was notified that after resuming from S3 sleep mode in various versions of BIOS for Lenovo systems, the PRx is not set. This does not impact the SMM BIOS Write Protection, which keeps systems protected.

A DLL search path vulnerability was reported in Lenovo Bootable Generator, prior to version Mar-2019, that could allow a malicious user with local access to execute code on the system.

An unquoted search path vulnerability was identified in Lenovo Dynamic Power Reduction Utility prior to version 2.2.2.0 that could allow a malicious user with local access to execute code with administrative privileges.

A vulnerability in the web interface of Lenovo EZ Media & Backup Center, ix2 & ix2-dl version 4.1.406.34763 and prior could allow an unauthenticated, remote attacker to redirect a user to an untrusted web page.

An internal product security audit of Lenovo XClarity Administrator (LXCA) discovered a Document Object Model (DOM) based cross-site scripting vulnerability in versions prior to 2.6.6 that could allow JavaScript code to be executed in the user's web browser if a specially crafted link is visited. The JavaScript code is executed on the user's system, not executed on LXCA itself.

An internal product security audit of Lenovo XClarity Administrator (LXCA) discovered Windows OS credentials, used to perform driver updates of managed systems, being written to a log file in clear text. This only affects LXCA version 2.6.0 when performing a Windows driver update. Affected logs are only accessible to authorized users in the First Failure Data Capture (FFDC) service log and log files on LXCA.

Incorrect parameter validation in the synaTee component of Synaptics WBF drivers using an SGX enclave (all versions prior to 2019-11-15) allows a local user to execute arbitrary code in the enclave (that can compromise confidentiality of enclave data) via APIs that accept invalid pointers.

Incorrect access control in the firmware of Synaptics VFS75xx family fingerprint sensors that include external flash (all versions prior to 2019-11-15) allows a local administrator or physical attacker to compromise the confidentiality of sensor data via injection of an unverified partition table.

In some Lenovo ThinkServer-branded servers, a command injection vulnerability exists in the BMC firmware download command. This allows a privileged user to download and execute arbitrary code inside the BMC. This can only be exploited by authorized privileged users.

A write protection lock bit was left unset after boot on an older generation of Lenovo and IBM System x servers, potentially allowing an attacker with administrator access to modify the subset of flash memory containing Intel Server Platform Services (SPS) and the system Flash Descriptors.

In System Management Module (SMM) versions prior to 1.06, if an attacker manages to log in to the device OS, the validation of software updates can be circumvented.

In System Management Module (SMM) versions prior to 1.06, the SMM contains weak default root credentials which could be used to log in to the device OS -- if the attacker manages to enable SSH or Telnet connections via some other vulnerability.

For some Iomega, Lenovo, LenovoEMC NAS devices versions 4.1.402.34662 and earlier, the password changing functionality available to authenticated users does not require the user's current password to set a new one. As a result, attackers with access to the user's session tokens can change their password and retain access to the user's account

For some Iomega, Lenovo, LenovoEMC NAS devices versions 4.1.402.34662 and earlier, the file name used for assets accessible through the Content Viewer application are vulnerable to self cross-site scripting self-XSS. As a result, adversaries can add files to shares accessible from the Content Viewer with a cross site scripting payload in its name, and wait for a user to try and rename the file for their payload to trigger.

For some Iomega, Lenovo, LenovoEMC NAS devices versions 4.1.402.34662 and earlier, by setting the Iomega cookie to a known value before logging into the NAS's web application, the NAS will not provide the user a new cookie value. This allows an attacker who knows the cookie's value to compromise the user's session.

For some Iomega, Lenovo, LenovoEMC NAS devices versions 4.1.402.34662 and earlier, adversaries can craft URLs to modify the Document Object Model (DOM) of the page. In addition, adversaries can inject HTML script tags and HTML tags with JavaScript handlers to execute arbitrary JavaScript with the origin of the device.

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.

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.

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.

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.

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 t ...
