The RC4 Bar Mitzvah Attack for SSL/TLS affects the Java JREs bundled with
WebSphere Dashboard Framework. These JREs are used to run the copies of
WebSphere Community Edition (WASCE) and Eclipse bundled with WebSphere
Dashboard Framework.
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".

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
All supported versions of WebSphere Dashboard Framework.
Remediation/Fixes
Obtain the JRE appropriate for you product from Fix Central. Note however that
these updated JREs are only appropriate for customers that have installed the
copy of Eclipse or WASCE bundled with WebSphere Dashboard Framework.
WebSphere Dashboard Framework 7.0.1 on Windows: LO84634.
WebSphere Dashboard Framework 7.0.1 on Linux: LO84669.
For unsupported versions of WebSphere Dashboard Framework IBM recommends
upgrading to a fixed and supported version of the product.
You should verify that applying these fixes does not cause any compatibility
issues. The fixes disable RC4 stream cipher by default. If you change this
default setting you 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.
Workarounds and Mitigations
None.
