Summary

SSL and TLS vulnerabilities were disclosed in September 2011. This vulnerability has been referred to as the “BEAST” attack. SSL protocol is used by SAN Volume Controller and Storwize Family.

Vulnerability Details

CVE-ID: CVE-2011-3389

DESCRIPTION: Multiple products could allow a remote attacker to obtain sensitive information, caused by a design error in the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols when using a Cipher-Block Chaining (CBC) based cryptographic algorithm. By persuading a victim to visit a Web site, a remote attacker could exploit this vulnerability using man-in-the-middle techniques to decrypt HTTPS sessions and obtain sensitive information.

CVSS Base Score: 4.3

Affected Products and Versions

IBM SAN Volume Controller
IBM Storwize V7000
IBM Storwize V5000
IBM Storwize V3700
IBM Storwize V3500

All products are affected when running supported releases 1.1 to 7.3. Release 7.4 is not affected once the minimum SSL protocol level has been set (see below).

Remediation/Fixes

IBM recommends that you fix this vulnerability by upgrading affected versions of IBM SAN Volume Controller, IBM Storwize V7000, V5000, V3700 and V3500 to the following code levels or higher:

7.3.0.10
7.4.0.4

Latest SAN Volume Controller Code
Latest Storwize V7000 Code
Latest Storwize V5000 Code
Latest Storwize V3700 Code
Latest Storwize V3500 Code

If running 7.4.0.0 code before 7.4.0.4, please run one of the following commands …

chsecurity -sslprotocol 2
chsecurity -sslprotocol 3

SAN Volume Controller 7.4 Knowledge Centre - chsecurity command

The default SSL protocol in 7.4.0.4 and 7.3.0.10 is not vulnerable and so running chsecurity not necessary.

IBM recommends that you review your entire environment to identify levels of SSL protocol being used.

Workarounds and Mitigations

Although IBM recommends that you install a level of code with a fix for this vulnerability, you can mitigate, although not eliminate, your risk until you have done so by ensuring that all users who have access to the system are authenticated by another security system such as a firewall.
