Apache Tomcat 7.0.x < 7.0.50 Multiple Vulnerabilities

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Apache Tomcat service may be affected by multiple
vulnerabilities.

Description :

According to its self-reported version number, the instance of Apache
Tomcat 7.0.x listening on the remote host is a version prior to
7.0.50. It is, therefore, potentially affected by the following
vulnerabilities :

- The fix for CVE-2012-3544 was not complete and limits
are not properly applied to chunk extensions and
whitespaces in certain trailing headers. This error
could allow denial of service attacks. (CVE-2013-4322)

- The application allows XML External Entity (XXE)
processing that could disclose sensitive information.
(CVE-2013-4590)

Note that Nessus did not actually test for these flaws, but instead
has relied on the version in Tomcat's banner or error page so this may
be a false positive.
