Description David Jorm 2014-08-14 00:58:41 UTC 
It was found that the fix for CVE-2012-5783 was incomplete. The code added to check that the server hostname matches the domain name in the subject's CN field was flawed. This can be exploited by a Man-in-the-middle (MITM) attack, where the attacker can spoof a valid certificate using a specially crafted subject.

Statement:

Additional information can be found in the Red Hat Knowledgebase article: https://access.redhat.com/solutions/1165533

This issue affects the versions of HttpComponents Client and ModeShape Client as shipped with Red Hat JBoss Data Virtualization 6. However, this flaw is not known to be exploitable under any supported scenario in Red Hat JBoss Data Virtualization 6. A future update may address this issue.

This issue did not affect the jakarta-commons-httpclient packages as shipped with Red Hat Enterprise Linux 5, 6, and 7, and httpcomponents-client packages as shipped with Red Hat Enterprise Linux 7.

Red Hat JBoss Enterprise Application Platform 4,  Red Hat JBoss SOA Platform 4, and Red Hat JBoss Web Server 1 are now in Phase 3, Extended Life Support, of their respective life cycles. This issue has been rated as having Important security impact and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat JBoss Middleware and Red Hat JBoss Operations Network Product Update and Support Policy: https://access.redhat.com/support/policy/updates/jboss_notes/

Fuse ESB 4, Fuse Message Broker 5.2, 5.3, 5.4 and Fuse Services Framework 2.3, 2.4 are now in a reduced support phase receiving only Critical impact security fixes. This issue has been rated as having Important security impact and is not currently planned to be addressed in future updates.

Comment 15 Arun Babu Neelicattu 2014-08-18 09:40:56 UTC 
The fix for the CVE-2014-3577 replaces the fix provided for issue CVE-2012-6153. Both CVE-2012-6153 and CVE-2012-5783 are considered to be resolved by a version of httpclient fixing CVE-2014-3577.

IssueDescription:

It was found that the fix for CVE-2012-5783 was incomplete: the code added to check that the server host name matches the domain name in a subject's Common Name (CN) field in X.509 certificates was flawed. A man-in-the-middle attacker could use this flaw to spoof an SSL server using a specially crafted X.509 certificate.

Comment 20 Tomas Hoger 2014-08-25 13:13:58 UTC 
The original issue CVE-2012-5783 was tracked via bug 873317.  That fix added support for checking of the connection host name against X.509 certificate host name, which was not performed before at all.  The check was implemented using the code that used string representation of the subject field, splitting it on commas, and checking each part to see if it contains "CN=" substring.

The fix applied upstream in version 4.2.3 that got CVE-2012-6153 assigned changed the code to only extract host name if subject attribute started with "CN=".  The fix prevented attacks using "CN=" string used as part of other subject attributes, such as organization ("O") or organizational unit ("OU").  I.e. it prevented certificate with the following subject to be accepted as valid for host "bank.com":

  OU=CN=bank.com,CN=evil.com

Even this improved fix was found to be incomplete, see CVE-2014-3577 (bug 1129074).

This erratum updated the thermostat1-httpcomponents-client package.  It incorrectly listed the package as affected by both CVE-2012-6153 and CVE-2014-3577, while it already contained the fix for CVE-2012-6153 and was only affected by CVE-2014-3577.

Comment 27 Tomas Hoger 2014-08-27 16:27:38 UTC 
This issue did not affect the jakarta-commons-httpclient packages shipped with Red Hat Enterprise Linux 5 and 6.  Updated packages to address CVE-2012-5783 released via RHSA-2013:0270 corrected that issue without introducing CVE-2012-6153.

The jakarta-commons-httpclient and httpcomponents-client packages shipped with Red Hat Enterprise Linux 7 were also not affected by this issue.

All mentioned packages are affected by CVE-2014-3577.
