-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss Enterprise Application Platform 7.0.9 security update Advisory ID: RHSA-2018:0003-01 Product: Red Hat JBoss Enterprise Application Platform Advisory URL: https://access.redhat.com/errata/RHSA-2018:0003 Issue date: 2018-01-03 CVE Names: CVE-2016-6346 CVE-2017-7559 CVE-2017-7561 CVE-2017-12165 CVE-2017-12167 CVE-2017-12189 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.
