Description

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.

Affected configurations

• lenovo xclarity controller (< 7.22 cdi382o) • lenovo xclarity controller (< 2.32 psi342n) • lenovo xclarity controller (< 3.41 tei382m) • lenovo xclarity controller (< 4.83 tei3c0n) • lenovo xclarity controller (< 1.51 tgbt24l)
