Name of the Vulnerable Software and Affected Versions: Lenovo XClarity Controller (XCC) (affected versions not specified)

Description: An internal product security audit 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.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
