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”.

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 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.

A command injection vulnerability was reported in some Lenovo Personal Cloud Storage devices that could allow an authenticated user to execute operating system commands by sending a crafted packet to the device.

A vulnerability was reported in some Lenovo Personal Cloud Storage devices that could allow an unauthenticated user to create a standard user account.

A weak default administrator password for the web interface and serial port was reported in some Lenovo Personal Cloud Storage devices that could allow unauthorized device access to an attacker with physical or local network access.

A weak default password for the serial port was reported in some Lenovo Personal Cloud Storage devices that could allow unauthorized device access to an attacker with physical access.

An information disclosure vulnerability was reported in some Lenovo Personal Cloud Storage devices that could allow an unauthenticated user to retrieve device and networking details.

A Time of Check Time of Use (TOCTOU) vulnerability was reported in IMController, a software component of Lenovo System Interface Foundation, prior to version 1.1.20.3that could allow a local attacker to elevate privileges.

A read-only authentication bypass vulnerability was reported in the Third Quarter 2021 release of Lenovo XClarity Controller (XCC) firmware affecting XCC devices configured in LDAP Authentication Only Mode and using an LDAP server that supports “unauthenticated bind”, such as Microsoft Active Directory. An unauthenticated user can gain read-only access to XCC in such a configuration, thereby allowing the XCC device configuration to be viewed but not changed. XCC devices configured to use local authentication, LDAP Authentication + Authorization Mode, or LDAP servers that support only “authenticated bind” and/or “anonymous bind” are not affected.

A race condition vulnerability was reported in IMController, a software component of Lenovo System Interface Foundation, prior to version 1.1.20.3 that could allow a local attacker to connect and interact with the IMController child process' named pipe.

A potential vulnerability due to improper buffer validation in the SMI handler LenovoFlashDeviceInterface in Thinkpad X1 Fold Gen 1 could be exploited by an attacker with local access and elevated privileges to execute arbitrary code.

During an internal product security audit a potential vulnerability due to use of Boot Services in the SmmOEMInt15 SMI handler was discovered in some ThinkPad models could be exploited by an attacker with elevated privileges that could allow for execution of code.

A denial of service vulnerability was reported in Lenovo Thin Installer prior to version 1.3.0039 that could trigger a system crash.

A vulnerability was reported in Lenovo System Update that could allow a local user with interactive system access the ability to execute code with elevated privileges only during the installation of a System Update package released before 2022-02-25 that displays a command prompt window.

A DLL search path vulnerability was reported in Lenovo PCManager prior to version 4.0.40.2175 that could allow privilege escalation.
