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
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/70069
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
Affected Products and Versions |
|---|
IBM SAN Volume Controller
Storwize V7000 for Lenovo
Storwize V5000 for Lenovo
Storwize V3700 for Lenovo
Storwize V3500 for Lenovo
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 |
|---|
Lenovo recommends that you fix this vulnerability by upgrading
affected versions of IBM SAN Volume Controller, Storwize V7000,
V5000, V3700 and V3500 for Lenovo to the following code level or
higher:
7.4.0.0
Latest SAN Volume Controller Code
Latest
Storwize V7000 Code
Latest
Storwize V5000 Code
Latest
Storwize V3700 Code
Latest
Storwize V3500 Code
Once you have upgraded the system you should use the CLI command
“lssecurity” to determine the current minimum level of
SSL protocol allowed. If it is less than level 3 (which allows only
TLS 1.2 with ciphers exclusive to TLS 1.2) then modify it with CLI
command “chsecurity”. This could cause systems
connected to this system via SSL to stop working because they
require upgrade or reconfiguration to allow them to use TLS 1.2
with exclusive ciphers. Upgrade those systems or use
“chsecurity” again to reduce the minimum level this
system uses until the connection works again.
The system is vulnerable until its SSL protocol level is set to 3
using “chsecurity”.

Lenovo recommends that you review your entire environment to
identify levels of SSL protocol being used.
Workarounds and Mitigations |
|---|
Although Lenovo 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.
