IBM Storwize SSL/TLS RC4 Stream Cipher Key Invariance (Bar Mitzvah)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote host is affected by a security feature bypass
vulnerability.

Description :

According to its self-reported version number, the IBM Storwize server
running on the remote host is affected by a security feature bypass
vulnerability, known as Bar Mitzvah, due to improper combination of
state data with key data by the RC4 cipher algorithm during the
initialization phase. A man-in-the-middle attacker can exploit this,
via a brute-force attack using LSB values, to decrypt the traffic.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.
