Vulnerabilidades

A privilege escalation vulnerability was reported in Lenovo Drivers Management Lenovo Driver Manager that could allow a local user to execute code with elevated privileges.

A valid, authenticated administrative user can query a web interface API to reveal the configured LDAP client password used by XCC to authenticate to an external LDAP server in certain configurations. There is no exposure where no LDAP client password is configured

A valid, authenticated XCC user with read-only permissions can modify custom user roles on other user accounts and the user trespass message through the XCC CLI. There is no exposure if SSH is disabled or if there are no users assigned optional read-only permissions.

A valid XCC user's local account permissions overrides their active directory permissions under specific configurations. This could lead to a privilege escalation. To be vulnerable, LDAP must be configured for authentication/authorization and logins configured as “Local First, then LDAP”.

A buffer overflow in the WMI SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to execute arbitrary code.

An information leak vulnerability in SMI Handler used to configure platform settings over WMI in some Lenovo models may allow an attacker with local access and elevated privileges to read SMM memory.

An information leak vulnerability in the Smart USB Protection SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to read SMM memory.

An information leak vulnerability in the SMI Set BIOS Password SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to read SMM memory.

The Remote Mount feature can potentially be abused by valid, authenticated users to make connections to internal services that may not normally be accessible to users. Internal service access controls, as applicable, remain in effect.

A buffer overflow exists in the Remote Presence subsystem which can potentially allow valid, authenticated users to cause a recoverable subsystem denial of service.

A potential vulnerability in a driver used during manufacturing process on the Ideapad Y700-14ISK that was mistakenly not deactivated may allow an attacker with elevated privileges to modify secure boot setting by modifying an NVRAM variable.

A buffer overflow in the SystemBootManagerDxe driver in some Lenovo Notebook products may allow an attacker with local privileges to execute arbitrary code.

A buffer overflow in the SystemLoadDefaultDxe driver in some Lenovo Notebook products may allow an attacker with local privileges to execute arbitrary code.

A buffer overflow in the ReadyBootDxe driver in some Lenovo Notebook products may allow an attacker with local privileges to execute arbitrary code.

A denial-of-service vulnerability has been identified in Lenovo Safecenter that could allow a local user to crash the application.

A potential vulnerability in the WMI Setup driver on some consumer Lenovo Notebook devices may allow an attacker with elevated privileges to modify secure boot setting by modifying an NVRAM variable.

An incorrect default permissions vulnerability in Lenovo Leyun cloud music application could allow denial of service.

A buffer over-read vulnerability was reported in the ThinkPadX13s BIOS LenovoRemoteConfigUpdateDxe driver that could allow a local attacker with elevated privileges to cause information disclosure.

A buffer over-read vulnerability was reported in the ThinkPadX13s BIOS driver that could allow a local attacker with elevated privileges to cause information disclosure.

A buffer over-read vulnerability was reported in the ThinkPadX13s BIOS LenovoSetupConfigDxe driver that could allow a local attacker with elevated privileges to cause information disclosure.

A buffer over-read vulnerability was reported in the ThinkPadX13s BIOS PersistenceConfigDxe driver that could allow a local attacker with elevated privileges to cause information disclosure.

Realtek Audio Drivers for Windows, as used on the Lenovo ThinkPad X1 Carbon 20A7, 20A8, 20BS, and 20BT before 6.0.8882.1 and 20KH and 20KG before 6.0.8907.1 (and on many other Lenovo and non-Lenovo products), mishandles DLL preloading.

ELAN Miniport touchpad Windows driver before 24.21.51.2, as used in PC hardware from multiple manufacturers, allows local users to cause a system crash by sending a certain IOCTL request, because that request is handled twice.

A potential vulnerability was reported in Lenovo PCManager prior to version 5.0.10.4191 that may allow code execution when visiting a specially crafted website.

A buffer overflow vulnerability in Lenovo Smart Standby Driver prior to version 4.1.50.0 could allow a local attacker to cause denial of service.
