In Undertow 2.x before 2.0.0.Alpha2, 1.4.x before 1.4.17.Final, and 1.3.x before 1.3.31.Final, 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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:0004 advisory.

    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).

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
