Security Bulletin
Summary
There are two vulnerabilities in Apache HTTPComponents that are used in IBM
WebSphere Application Server. Although IBM WebSphere Application server is not
vulnerable to these, other products or applications that use these libraries
could be vulnerable.
Vulnerability Details
CVEID: CVE-2012-6153
DESCRIPTION: Apache HttpComponents could allow a remote attacker to conduct
spoofing attacks, caused by an incomplete fix related to the failure to verify
that the server hostname matches a domain name in the Subject's Common Name
(CN) or SubjectAltName field of certificates. By persuading a victim to visit
a Web site containing a specially-crafted certificate, an attacker could
exploit this vulnerability using man-in-the-middle techniques to spoof an SSL
server.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95328 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
Affected Products and Versions
These vulnerabilities affect the following versions and releases of IBM
WebSphere Application Server
Version 8.5.5 Full Profile
Version 8.5 Full Profile
Version 8.0
Remediation/Fixes
The interim fix for this issue hides the Apache HttpComponents from being
visible to other products or applications. This is a change back to the
original behavior in releases prior to Version 8. If you install the interim
fix or the fixpack containing this APAR you may notice a change if your
application is relying on the HttpComponents shipped by WebSphere Application
Server. If you see a NoClassDefFoundError observed after applying the fix, it
is because the API in HttpComponents libraries are no longer visible to your
application.
To resolve this error, your application may need to be updated to add the
HttpComponents library into your application. Please refer to the Apache
website for information and download: Apache HttpComponents
The recommended solution is to apply the interim fix, Fix Pack or PTF
containing APAR PI50993 for each named product as soon as practical.
For WebSphere Application Server:
For V8.5.0.0 through 8.5.5.8 Full Profile:
Upgrade to minimal fix pack levels as required by interim fix and then apply
Interim Fix PI50993
- --OR--
Apply Fix Pack 8.5.5.9 or later (targeted availability 18 March 2016).
For V8.0 through 8.0.0.11:
Upgrade to a minimal fix pack levels as required by interim fix and then
apply Interim Fix PI50993
- --OR--
Apply Fix Pack 8.0.0.12 or later (targeted availability 01 February 2016).
