TITLE

Apache Tomcat Vulnerability that could bypass the security manager limitation in the default servlet

DESCRIPTION

java/org/apache/catalina/servlets/DefaultServlet.java in the default servlet in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 does not properly restrict XSLT stylesheets, which allows remote attackers to bypass security-manager restrictions and read arbitrary files via a crafted web application that provides an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: tomcat security update Advisory ID: RHSA-2014:0827-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0827.html Issue date: 2014-07-02 CVE Names: CVE-2014-0075 CVE-2014-0096 CVE-2014-0099 ===================================================================== 1. Summary: Updated tomcat packages that fix three security issues are now available for Red Hat Enterprise Linux 7. The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - noarch Red Hat Enterprise Linux Client Optional (v. 7) - noarch Red Hat Enterprise Linux ComputeNode (v. 7) - noarch Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch Red Hat Enterprise Linux Server (v. 7) - noarch Red Hat Enterprise Linux Server Optional (v. 7) - noarch Red Hat Enterprise Linux Workstation (v. 7) - noarch Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch 3. Description: Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. It was discovered that Apache Tomcat did not limit the length of chunk sizes when using chunked transfer encoding. A remote attacker could use this flaw to perform a denial of service attack against Tomcat by streaming an unlimited quantity of data, leading to excessive consumption of server resources. (CVE-2014-0075) It was found that Apache Tomcat did not check for overflowing values when parsing request content length headers. A remote attacker could use this flaw to perform an HTTP request smuggling attack on a Tomcat server located behind a reverse proxy that processed the content length header correctly. (CVE-2014-0099) It was found that the org.apache.catalina.servlets.DefaultServlet implementation in Apache Tomcat allowed the definition of XML External Entities (XXEs) in provided XSLTs. A malicious application could use this to circumvent intended security restrictions to disclose sensitive information. (CVE-2014-0096) The CVE-2014-0075 issue was discovered by David Jorm of Red Hat Product Security. All Tomcat 7 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. Tomcat must be restarted for this update to take effect. 4.

Apache Tomcat 7.x before 7.0.50 processes chunked transfer coding without properly handling (1) a large total amount of chunked data or (2) whitespace characters in an HTTP header value within a trailer field, which allows remote attackers to cause a denial of service by streaming data (CVE-2013-4322). In Apache Tomcat 7.x before 7.0.55, it was possible to craft a malformed chunk as part of a chunked request that caused Tomcat to read part of the request body as a new request (CVE-2014-0227).
