It was found in Undertow before 1.3.28 that with non-clean TCP close, the Websocket server gets into infinite loop on every IO thread, effectively causing DoS.

An update is now available for Red Hat JBoss Enterprise Application Platform 7.0 for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. 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.

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 7.0.6 serves as a replacement for Red Hat JBoss Enterprise Application Platform 7.0.5, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.

Security Fix(es) :

* It was discovered that under certain conditions RESTEasy could be forced to parse a request with YamlProvider, resulting in unmarshalling of potentially untrusted data. An attacker could possibly use this flaw execute arbitrary code with the permissions of the application using RESTEasy. (CVE-2016-9606)

* It was found that the log file viewer in Red Hat JBoss Enterprise Application 6 and 7 allows arbitrary file read to authenticated user via path traversal. (CVE-2017-2595)

* It was discovered that the code that parsed the HTTP request line permitted invalid characters. 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-2017-2666)

* It was found that with non-clean TCP close, Websocket server gets into infinite loop on every IO thread, effectively causing DoS.

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.

Two vulnerabilities have been discovered in Undertow, a web server written in Java, which may lead to denial of service or HTTP request smuggling.
