CVE-2014-0096

TITLE

Apache Tomcat Permission Licensing and Access Control Issue Vulnerability

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. Apache Tomcat is prone to an information-disclosure vulnerability. An attacker can exploit this issue to gain access to sensitive information that may lead to further attacks. The following versions are vulnerable: Apache Tomcat 8.0.0-RC1 to 8.0.3 Apache Tomcat 7.0.0 to 7.0.52 Apache Tomcat 6.0.0 to 6.0.39. Description: Red Hat JBoss Data Grid is a distributed in-memory data grid, based on Infinispan. It includes various bug fixes and enhancements which are detailed in the Red Hat JBoss Data Grid 6.3.0 Release Notes. (CVE-2014-0099) It was found that the security audit functionality, provided by Red Hat JBoss Data Grid, logged request parameters in plain text. This may have caused passwords to be included in the audit log files when using BASIC or FORM-based authentication. A local attacker with access to audit log files could possibly use this flaw to obtain application or server authentication credentials. Refer to the Solution section of this advisory for additional information on the fix for this issue. (CVE-2014-0096) It was found that, in certain circumstances, it was possible for a malicious web application to replace the XML parsers used by JBoss Web to process XSLTs for the default servlet, JSP documents, tag library descriptors (TLDs), and tag plug-in configuration files. The injected XML parser(s) could then bypass the limits imposed on XML external entities and/or gain access to the XML files processed for other web applications deployed on the same JBoss Web instance. Solution: The References section of this erratum contains a download link (you must log in to download the update). Before applying this update, back up your existing JBoss Data Grid installation. The provided patch to fix CVE-2014-0058 also allows greater control over which of the following components of web requests are captured in audit logs: - - parameters - - cookies - - headers - - attributes It is also possible to selectively mask some elements of headers, parameters, cookies, and attributes using masks. This capability is provided by two system properties, which are introduced by this patch: 1) org.jboss.security.web.audit Description: This property controls the granularity of the security auditing of web requests. Possible values: off = Disables auditing of web requests headers = Audits only the headers of web requests cookies = Audits only the cookies of web requests parameters = Audits only the parameters of web requests attributes = Audits only the attributes of web requests headers,cookies,parameters = Audits the headers, cookies, and parameters of web requests headers,cookies = Audits the headers and cookies of web requests Default Value: headers, parameters Examples: Setting "org.jboss.security.web.audit=off" disables security auditing of web requests entirely. Setting "org.jboss.security.web.audit=headers" enables security auditing of only headers in web requests. 2) org.jboss.security.web.audit.mask Description: This property can be used to specify a list of strings to be matched against headers, parameters, cookies, and attributes of web requests. Any element matching the specified masks will be excluded from security audit logging. Possible values: Any comma separated string indicating keys of headers, parameters, cookies, and attributes. Default Value: j_password, authorization Note that currently the matching of the masks is fuzzy rather than strict. For example, a mask of "authorization" will mask both the header called authorization and the parameter called "custom_authorization". A future release may introduce strict masks. -----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.

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).
