It was discovered that sending specially crafted HTTP request to the JON server would allow deserialization of that message without authentication. An attacker could use this flaw to cause remote code execution.

Red Hat Product Errata RHSA-2016:1519 normal SHIPPED_LIVE Critical: Red Hat JBoss Operations Network 3.3.6 update 2016-08-26 00:44:36 UTC

Description Jason Shepherd 2016-05-06 02:20:35 UTC
JBoss Operations Network server deserializes data, and does not require authentication. A malicious payload could be crafted, and sent to a server which when deserialized causes remote code execution.

A workaround for this issue it to enable client authentication between servers and agents:

Comment 9 errata-xmlrpc 2016-07-27 15:31:47 UTC
This issue has been addressed in the following products:

   Red Hat JBoss Operations Network 3.3.6 

Via RHSA-2016:1519 https://rhn.redhat.com/errata/RHSA-2016-1519.html

Comment 10 Jason Shepherd 2016-08-11 23:55:02 UTC
Despite it previously being described as a workaround, the configuration change documented below is the actual solution to this issue.

Comment 11 Jason Shepherd 2016-08-18 00:59:57 UTC
Mitigation:

Apply the configuration changes described in the documentation here: https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Operations_Network/3.3/html/Admin_and_Config/JBoss_ON_and_SSL-Authentication.html
For more information, refer to https://access.redhat.com/articles/2570101.

Comment 12 Jason Shepherd 2016-08-18 01:01:21 UTC
Statement:

It is not feasible to correct this issue with a code change as client SSL certificates need to be created in order to support client authentication.  The installation documentation notes how to mitigate this through the creation of certificates to support SSL authentication.  This mitigation is the best way to correct this issue and, as a result, we will not be releasing any patches to correct the issue.
