Summary
Fixes are available for Security Vulnerabilities in Apache HttpComponents that
affect IBM WebSphere Portal (CVE-2012-6153; CVE-2014-3577)
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

Affected Products and Versions
WebSphere Portal 8.5

WebSphere Portal 7
WebSphere Portal 6.1
Remediation/Fixes
The recommended solution is to apply fixes as soon as practical.
Fix: Apply an Interim Fix or a Cumulative Fix containing the listed fixes.
Note that the JAR files may not be removed by a specific interim fix but the
interim fix will remove all WebSphere Portal uses of those JAR files.
The JAR files will be removed by the next Cumulative Fix associated with that
release.
After the interim fixes are applied on your system from a WebSphere Portal
Product view it is possible to remove the Apache commons-httpclient JAR files
manually or wait for the next CF to do so:
commons-httpclient-2.0.jar
commons-httpclient-3.0.jar
commons-httpclient-3.0.1.jar
For 8.5.0
Upgrade to Cumulative Fix 04 (CF04) and then apply the Interim Fix
PI26975, PI26981, PI32251, PI33739
(Combined Cumulative Fixes for WebSphere Portal 8.5.0.0:
http://www-01.ibm.com/support/docview.wss?uid=swg24037786)
For 8.0.0 through 8.0.0.1
Upgrade to Fix Pack 8.0.0.1 with Cumulative Fix 15 (CF15).
(Combined Cumulative Fixes for WebSphere Portal 8.0.0.1:
http://www-01.ibm.com/support/docview.wss?uid=swg24034497)
For 7.0.0 through 7.0.0.2
Upgrade to Fix Pack 7.0.0.2 with Cumulative Fix 29 (CF29) and then apply
the Interim Fix PI25512 PI26976, PI26980, PI32251
(Combined Cumulative fixes for WebSphere Portal 7.0.0.2:
http://www.ibm.com/support/docview.wss?uid=swg24029452)
For 6.1.5.0 through 6.1.5.3
Upgrade to Fix Pack 6.1.5.3 with Cumulative Fix 27 (CF27) and then apply
the Interim Fix PI25512, PI26976, PI26977, PI26980, PI32251
(Cumulative fixes for WebSphere Portal 6.1.5.3:
http://www-01.ibm.com/support/docview.wss?uid=swg24023835)
For 6.1.0.0 through 6.1.0.6
Upgrade to Fix Pack 6.1.0.6 with Cumulative Fix 27 (CF27) and then apply
the Interim Fix PI25512, PI26976, PI26977, PI26980, PI32251
(Cumulative fixes for WebSphere Portal 6.1.0.6:
http://www-01.ibm.com/support/docview.wss?uid=swg24023835)
Workarounds and Mitigations
If you do not have any custom code or third party code that uses these JAR
files you do not have to do anything as consequence of this removal.
If you do have custom code or third party code that depends on these JAR files
to be in the Portal Server classpath then you will have to make a change.
There are many options. You can simply add a copy of the JAR back into the
WebSphere Application Server or WebSphere Portal classpath, add the JAR into
the appropriate portlet WAR file (neither of which will protect you from the
security vulnerabilities) or change your custom source code to use the new
Apache HttpClient 4.3.6 JAR that does fix the security vulnerability. Changing
the source code is the best option. Note that Apache HttpClient 4.3.6 is a
complete rewrite of the library and there is no backward compatibility.
Reference the Apache web site for more details.
