Summary

The RC4 “Bar Mitzvah” Attack for SSL/TLS affects IBM XIV Management Tools.

Vulnerability Details

CVEID: CVE-2015-2808 DESCRIPTION: The RC4 algorithm, as used in the TLS protocol and SSL protocol, could allow a remote attacker to obtain sensitive information. An attacker could exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation could allow an attacker to retrieve credit card data or other sensitive information. This vulnerability is commonly referred to as “Bar Mitzvah Attack”.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101851 for the current score
CVSS Environmental Score*: Undefined

Affected Products and Versions

IBM XIV Management Tools, all releases up to and including 4.5

Remediation/Fixes

See “Workarounds and Mitigations” below.

Workarounds and Mitigations

For the IBM XIV XCLI and XIV GUI, edit the file <install-dir>\jre\lib\security\java.security: change the last line to “jdk.tls.disabledAlgorithms=SSLv3, RC4”. After editing and saving, restart the application.

For the IBM Hyper-Scale Manager, edit the file $JAVA_IBM_HOME/lib/security/java.security, where JAVA_IBM_HOME is by default /home/msms/hyperscale/jre, and change the last line to “jdk.tls.disabledAlgorithms=SSLv3, RC4”. After editing and saving, restart the application.

You should verify applying this fix does not cause any compatibility issues. The fix disables RC4 stream cipher by default.

IBM recommends that you review your entire environment to identify other areas where you have enabled the RC4 stream cipher and take appropriate mitigation and remediation actions.
