Summary

The RC4 Bar Mitzvah Attack for SSL/TLS affects IBM Rational ClearQuest.

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

IBM Rational ClearQuest, versions 7.1.0.x, 7.1.1.x, 7.1.2.x, 8.0.0.x, 8.0.1.x,
in the following components:

ClearQuest Eclipse clients that use Report Designer, run remote reports on
servers using secure connections, or use the embedded browser to connect to 
secure web sites.

ClearQuest Web Server with SSL enabled

Remediation/Fixes

The fix depends on the component you use that is affected by this 
vulnerability:

ClearQuest Eclipse client component

1) Upgrade ClearQuest

Affected Versions	        Fix Pack needed before applying test fix

8.0.1.x		        	Install Rational ClearQuest Fix Pack 7 (8.0.1.7)

8.0.0.x		        	Install Rational ClearQuest Fix Pack 14 (8.0.0.14)

7.1.2.x				Customers with extended support contracts should install Rational ClearQuest Fix Pack 17 (7.1.2.17)
7.1.1.x
7.1.0.x

        	

2) After installing the appropriate Fix Pack, contact IBM support for
instructions to download and install the additional fix.

ClearQuest Web Server component

The solution is to apply fixes or mitigations to your IBM WebSphere 
Application Server (WAS) and IBM HTTP Server (IHS) components.

If your clients connect to IHS via SSL (which then redirects their 
connections to WAS), then review this IHS bulletin: Security Bulletin: 
Vulnerability in RC4 stream cipher affects IBM HTTP Server (CVE-2015-2808) and
apply fixes or remediations to your server.

If your clients connect directly to WAS with SSL, then review this 
bulletin for instructions on applying a mitigation or fix to your WAS 
installation and your ClearCase profile:

Security Bulletin: Vulnerability in RC4 stream cipher affects 
WebSphere Application Server (CVE-2015-2808).

Depending on your version of ClearQuest, you may need additional steps
when installing IHS or WAS fixes:

Affected Versions	        	Applying the fix

7.1.0.x, 7.1.1.x, and 7.1.2.x 		Document 1390803 explains how to update 
					WebSphere Application Server and/or IBM 
					HTTP Server for ClearQuest Web Servers
					at release 7.1.x. Consult those 
					instructions when applying the fix.

        8.0.0.x
        8.0.1.x 			Apply the appropriate WebSphere 
					Application Server and/or IBM HTTP 
					Server fix directly to your ClearQuest 
					Web server host. No ClearQuest-specific
					steps are necessary.

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

For unsupported versions, IBM recommends upgrading to a fixed, supported 
version/release/platform of the product.
