https://notcve.org/view.php?id=CVE-2021-3956
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 •
CVE-2021-3473
https://notcve.org/view.php?id=CVE-2021-3473
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 •
