Lenovo ThinkAgile MX1021 - any version

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 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.

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.
