An uncontrolled search path vulnerability was reported in the Lenovo Universal Device Client (UDC) that could allow an attacker with local access to execute code with elevated privileges.

A buffer overflow has been identified in the SetupUtility driver in some Lenovo Notebook products which may allow an attacker with local access and elevated privileges to execute arbitrary code.

An unauthenticated XML external entity injection (XXE) vulnerability exists in LXCA's Common Information Model (CIM) server that could result in read-only access to specific files.

A valid, authenticated LXCA user with elevated privileges may be able to delete folders in the LXCA filesystem through a specifically crafted web API call due to insufficient input validation.

A valid, authenticated LXCA user with elevated privileges may be able to replace filesystem data through a specifically crafted web API call due to insufficient input validation.

A valid, authenticated LXCA user with elevated privileges may be able to execute command injections through crafted calls to a specific web API.

A valid, authenticated LXCA user may be able to gain unauthorized access to events and other data stored in LXCA due to a SQL injection vulnerability in a specific web API.

A valid, authenticated user with limited privileges may be able to use specifically crafted web management server API calls to execute a limited number of commands on SMM v1, SMM v2, and FPC that the user does not normally have sufficient privileges to execute.

An unauthenticated denial of service vulnerability exists in the SMM v1, SMM v2, and FPC management web server which can be triggered under crafted conditions. Rebooting SMM or FPC will restore access to the management web server.

A potential vulnerability in the LenovoFlashDeviceInterface SMI handler may allow an attacker with local access and elevated privileges to execute arbitrary code.
