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. • https://support.lenovo.com/us/en/product_security/LEN-72074 • CWE-863: Incorrect Authorization •

An internal product security audit of Lenovo XClarity Controller (XCC) discovered that the XCC configuration backup/restore password may be written to an internal XCC log buffer if Lenovo XClarity Administrator (LXCA) is used to perform the backup/restore. The backup/restore password typically exists in this internal log buffer for less than 10 minutes before being overwritten. Generating an FFDC service log will include the log buffer contents, including the backup/restore password if present. The FFDC service log is only generated when requested by a privileged XCC user and it is only accessible to the privileged XCC user that requested the file. The backup/restore password is not captured if the backup/restore is initiated directly from XCC. • https://support.lenovo.com/us/en/product_security/LEN-52117 • CWE-312: Cleartext Storage of Sensitive Information CWE-319: Cleartext Transmission of Sensitive Information •

An authorization bypass exists in Lenovo XClarity Controller (XCC) versions prior to 3.08 CDI340V, 3.01 TEI392O, 1.71 PSI328N where a valid authenticated user with lesser privileges may be granted read-only access to higher-privileged information if 1) “LDAP Authentication Only with Local Authorization” mode is configured and used by XCC, and 2) a lesser privileged user logs into XCC within 1 minute of a higher privileged user logging out. The authorization bypass does not exist when “Local Authentication and Authorization” or “LDAP Authentication and Authorization” modes are configured and used by XCC. Se presenta una omisión de autorización en Lenovo XClarity Controller (XCC) versiones anteriores a 3.08 CDI340V, versión 3.01 TEI392O, versión 1.71 PSI328N, donde un usuario autenticado válido con privilegios menores puede tener acceso de solo de lectura a información con privilegios superiores si 1) "LDAP Authentication Only with Local Authorization” es configurado y utilizado por XCC, y 2) un usuario con menos privilegios inicia sesión en XCC dentro de 1 minuto después de que un usuario con mayor privilegio cierre sesión. La omisión de autorización no se presenta cuando los modos “Local Authentication and Authorization” o “LDAP Authentication and Authorization” son configurados y utilizados por XCC. • https://support.lenovo.com/us/en/product_security/LEN-29116 • CWE-264: Permissions, Privileges, and Access Controls CWE-269: Improper Privilege Management •
