Lenovo : Security Vulnerabilities, CVEs, Published In October 2020

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 as allowed by defined ACLs. Lenovo strongly recommends upgrading to a non-vulnerable CNOS release. Where not possible, Lenovo recommends disabling the REST API management interface or restricting access to the management VRF and further limiting access to authorized management stations via ACL.

A DLL search path vulnerability was reported in the Lenovo HardwareScan Plugin for the Lenovo Vantage hardware scan feature prior to version 1.0.46.11 that could allow escalation of privilege.

A DLL search path vulnerability was reported in Lenovo Diagnostics prior to version 4.35.4 that could allow a user with local access to execute code on the system.

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.
