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.
