Descriptions

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.

Se ha informado de una vulnerabilidad de elusión de autenticación de solo lectura en la versión del tercer trimestre de 2021 del firmware de Lenovo XClarity Controller (XCC) que afecta a los dispositivos XCC configurados en el modo de solo autenticación LDAP y que usan un servidor LDAP que admite €œunauthenticated bindâ€?, como Microsoft Active Directory. Un usuario no autenticado puede conseguir acceso de sólo lectura al XCC en dicha configuración, lo que permite visualizar la configuración del dispositivo XCC pero no modificarla. Los dispositivos XCC configurados para usar la autenticación local, el modo de autenticación + autorización LDAP o los servidores LDAP que sólo admiten la "vinculación autenticada" y/o la "vinculación anónima" no están afectados
