Security Bulletin

Summary

The RC4 Bar Mitzvah Attack for SSL/TLS affects IBM Integration Designer and 
WebSphere Integration Developer.

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

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

Affected Products and Versions

This vulnerability affects IBM Integration Designer and WebSphere Integration
Developer.

Remediation/Fixes

To fully mitigate these vulnerabilities, an additional fix (JR53201) is 
required for IBM Integration Designer V7.5.1.2 and V8.0.1.3 and WebSphere 
Integration Developer V7.0.0.5:

   WebSphere Integration Developer V7.0.0.5

   IBM Integration Designer V7.5.1.2

   IBM Integration Designer V8.0.1.3

Workarounds and Mitigations

If you are using any of the following products:

   IBM Integration Designer V8.5

   IBM Integration Designer V8.5.5.0

   IBM Integration Designer V8.5.6.0

then the following steps can be used to remove RC4 from the list of available
algorithms:

Prerequisite: Before removing RC4 from the list of available algorithms, you 
must first install the FREAK: Factoring Attack on RSA-EXPORT keys fix. See 
this document for more information.

1. Ensure that the product is not running.

2. Locate the java.security file used by the product from the following 
location:

install folder/jdk/jre/lib/security/java.security

3. Edit the java.security file with a text editor and locate the line:

jdk.tls.disabledAlgorithms=SSLv3

4. Add RC4 to the list of disabled algorithms, for example:

jdk.tls.disabledAlgorithms=SSLv3, RC4

5. Save the file and restart the product.

You should verify applying this configuration change does not cause any 
compatibility issues. Not disabling the RC4 stream cipher will expose yourself
to the attack described above. 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.
