CVE-2017-12629
=====================================================================

1. Summary:

An update is now available for Red Hat JBoss Enterprise Application
Platform.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Description:

Red Hat JBoss Enterprise Application Platform is a platform for Java
applications based on the JBoss Application Server.

This release of Red Hat JBoss Enterprise Application Platform 7.0.9 serves
as a replacement for Red Hat JBoss Enterprise Application Platform 7.0.8,
and includes bug fixes and enhancements, which are documented in the
Release Notes document linked to in the References.

Security Fix(es):

* It was found that Apache Lucene would accept an object from an
unauthenticated user that could be manipulated through subsequent post
requests. An attacker could use this flaw to assemble an object that could
permit execution of arbitrary code if the server enabled Apache Solr's
Config API. (CVE-2017-12629)

* It was discovered that the jboss init script performed unsafe file
handling which could result in local privilege escalation. (CVE-2017-12189)

* It was found that GZIPInterceptor is enabled when not necessarily
required in RESTEasy. An attacker could use this flaw to launch a Denial of
Service attack. (CVE-2016-6346)

* It was found that the fix for CVE-2017-2666 was incomplete and invalid
characters are still allowed in the query string and path parameters. This
could be exploited, in conjunction with a proxy that also permitted the
invalid characters but with a different interpretation, to inject data into
the HTTP response. By manipulating the HTTP response the attacker could
poison a web-cache, perform an XSS attack, or obtain sensitive information
from requests other than their own. (CVE-2017-7559)

* It was discovered that the CORS Filter did not add an HTTP Vary header
indicating that the response varies depending on Origin. This permitted
client and server side cache poisoning in some circumstances.
(CVE-2017-7561)

* It was found that properties based files of the management and the
application realm configuration that contain user to role mapping are world
readable allowing access to users and roles information to all the users
logged in to the system. (CVE-2017-12167)

* It was discovered that Undertow processes http request headers with
unusual whitespaces which can cause possible http request smuggling.
(CVE-2017-12165)

Red Hat would like to thank Mikhail Egorov (Odin) for reporting
CVE-2016-6346. The CVE-2017-7559 and CVE-2017-12165 issues were discovered
by Stuart Douglas (Red Hat); the CVE-2017-7561 issue was discovered by
Jason Shepherd (Red Hat Product Security); and the CVE-2017-12167 issue was
discovered by Brian Stansberry (Red Hat) and Jeremy Choi (Red Hat).
