Security Bulletin: Java vulnerability on IBM SAN Volume Controller and Storwize Family (CVE-2014-0411)

Security Bulletin

Summary

Java vulnerability could allow decryption of long GUI session

Vulnerability Details

CVEID:
CVE-2014-0411

DESCRIPTION:

Java is used in the system’s GUI. Timing differences based on the validity of messages can be exploited to decrypt the entire session. The exploit is not trivial, requiring a man-in-the-middle position and an extended period of time (around 20 hours). Decryption of the session could give the attacker access to user credentials.

CVE-2014-0411
CVSS Base Score: 4
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/90357 for the current score

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

All products are affected when running code releases 6.1, 6.2, 6.3, 6.4, 7.1 and 7.2. Code release 7.3 is not vulnerable.

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 and IBM Flex System V7000 to the following code level or higher:

7.3.0.3

Latest SAN Volume Controller Code
Latest Storwize V7000 Code
Latest Storwize V5000 Code
Latest Storwize V3700 Code
Latest Storwize V3500 Code
Latest IBM Flex System V7000 Code

Workarounds and Mitigations

Limit the length of GUI sessions to less than 20 hours.

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.
