SC4020 reported as critical vulnerability by Nessus

Our SC4020 disk array has been recognized as critical vulnerability by Nessus vulnerability scan software.

It is due the unsupported version of OS – FreeBSD 9.2. Here is the message from the scan:

Unsupported Unix Operating System

According to its version, the remote Unix operating system is no longer supported.

Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.
Upgrade to a more recent version that is currently supported.


The installed version of SCOS is 6.5.3. How is it possible to solve this problem – Is it possible to upgrade the FreeBSD OS to the supported version with the SCOS upgrade?
