In some Lenovo Desktop models, the Configuration Change Detection BIOS setting failed to detect SATA configuration changes.

An authentication bypass vulnerability was reported in Lenovo ThinkPad Stack Wireless Router firmware version 1.1.3.4 that could allow escalation of privilege.

An internal security review has identified an unauthenticated remote code execution vulnerability in Cloud Networking Operating System (CNOS)’ optional REST API management interface. This interface is disabled by default and not vulnerable unless enabled. When enabled, it is only vulnerable where attached to a VRF and…

A potential vulnerability in the SMI callback function used in the legacy BIOS mode USB drivers in some legacy Lenovo and IBM System x servers may allow arbitrary code execution. Servers operating in UEFI mode are not affected.

A DOM-based cross-site scripting (XSS) vulnerability was reported in Lenovo Enterprise Network Disk prior to version 6.1 patch 6 hotfix 4 that could allow execution of code in an authenticated user's current browser session if a crafted url is visited, possibly through phishing.

A reflective cross-site scripting (XSS) vulnerability was reported in Lenovo Enterprise Network Disk prior to version 6.1 patch 6 hotfix 4 that could allow execution of code in an authenticated user's browser if a crafted url is visited, possibly through phishing.

A potential vulnerability in the SMI callback function used in the EEPROM driver in some Lenovo Desktops and ThinkStation models may allow arbitrary code execution

A denial of service vulnerability was reported in the Lenovo Vantage component called Lenovo System Interface Foundation prior to version 1.1.19.5 that could allow configuration files to be written to non-standard locations.

A race condition vulnerability was reported in Lenovo System Update prior to version 5.07.0106 that could allow escalation of privilege.

A cross-site scripting (XSS) vulnerability was discovered in the legacy IBM and Lenovo System x IMM2 (Integrated Management Module 2), prior to version 5.60, embedded Baseboard Management Controller (BMC) web interface during an internal security review. This vulnerability could allow JavaScript code to be executed in…

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). After resuming from S3 sleep mode in various versions of BIOS for some Lenovo ThinkPad systems, the PRx…

The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad A285, BIOS versions up to r0xuj70w; A485, BIOS versions up to r0wuj65w; T495 BIOS versions up to r12uj55w; T495s/X395, BIOS versions up to r13uj47w, while the emergency-reset button is pressed which may allow for unauthorized access.

An unquoted service path vulnerability was reported in Lenovo Drivers Management prior to version 2.7.1128.1046 that could allow an authenticated user to execute code with elevated privileges.

A DLL search path vulnerability was reported in Lenovo Drivers Management prior to version 2.7.1128.1046 that could allow an authenticated user to execute code with elevated privileges.

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.

Lenovo implemented Intel CSME Anti-rollback ARB protections on some ThinkPad models to prevent roll back of CSME Firmware in flash.

The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad T495s, X395, T495, A485, A285, A475, A275 which may allow for unauthorized access.

A potential vulnerability in the SMI callback function used in the Legacy SD driver in some Lenovo ThinkPad, ThinkStation, and Lenovo Notebook models may allow arbitrary code execution.

A potential vulnerability in the SMI callback function used in the Legacy USB driver in some Lenovo Notebook and ThinkStation models may allow arbitrary code execution.

A potential vulnerability in the SMI callback function used in the System Lock Preinstallation driver in some Lenovo Notebook and ThinkStation models may allow arbitrary code execution.

An internal shell was included in BIOS image in some ThinkPad models that could allow escalation of privilege.
