The RC4 Bar Mitzvah Attack for SSL/TLS affects IBM Integration Designer and
WebSphere Integration Developer.
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
CVSS Base Score: 5

Affected Products and Versions
This vulnerability affects IBM Integration Designer and WebSphere Integration
To fully mitigate these vulnerabilities, an additional fix (JR53201) is
required for IBM Integration Designer V22.214.171.124 and V126.96.36.199 and WebSphere
Integration Developer V188.8.131.52:
WebSphere Integration Developer V184.108.40.206

IBM Integration Designer V18.104.22.168
Workarounds and Mitigations
If you are using any of the following products:
IBM Integration Designer V8.5
IBM Integration Designer V22.214.171.124
IBM Integration Designer V126.96.36.199
then the following steps can be used to remove RC4 from the list of available
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
3. Edit the java.security file with a text editor and locate the line:
4. Add RC4 to the list of disabled algorithms, for example:
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.
