Lenovo XClarity Controller (XCC) Information Disclosure Vulnerability - Lenovo Support NL

**Lenovo Security Advisory:**LEN-52117

**Potential Impact:**Information disclosure

**Severity:**Medium

**Scope of Impact:**Lenovo-specific

**CVE Identifier:**CVE-2021-3473

Summary Description:

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.

Mitigation Strategy for Customers (what you should do to protect yourself):

Update to the Lenovo XClarity Controller (XCC) version (or higher) as recommended in the Product Impact section below.
