DESCRIPTION

* CVE-2020-28374: Access control bypass when reading or writing TCM devices.

Lack of validation against the session's list when matching a Target Core
Mod (TCM) device during an eXtended COPY (XCOPY) operation leads to access
control bypass.  Attackers with access to one device could read and write
from/to other devices they should not have access to.
