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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: Red Hat JBoss Data Grid 6.3.0 update Advisory ID: RHSA-2014:0895-01 Product: Red Hat JBoss Data Grid Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0895.html Issue date: 2014-07-16 CVE Names: CVE-2014-0058 CVE-2014-0059 CVE-2014-0075 CVE-2014-0096 CVE-2014-0099 CVE-2014-0119 ===================================================================== 1. Summary: Red Hat JBoss Data Grid 6.3.0, which fixes multiple security issues, various bugs, and adds enhancements, is now available from the Red Hat Customer Portal. 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. Description: Red Hat JBoss Data Grid is a distributed in-memory data grid, based on Infinispan. This release of Red Hat JBoss Data Grid 6.3.0 serves as a replacement for Red Hat JBoss Data Grid 6.2.1. It includes various bug fixes and enhancements which are detailed in the Red Hat JBoss Data Grid 6.3.0 Release Notes. The Release Notes will be available shortly from https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Data_Grid/ This update also fixes the following security issues: It was discovered that JBoss Web 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 JBoss Web by streaming an unlimited quantity of data, leading to excessive consumption of server resources. (CVE-2014-0075) It was found that JBoss Web 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 JBoss Web server located behind a reverse proxy that processed the content length header correctly. (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-2014-0058) It was found that the security auditing functionality provided by PicketBox and JBossSX, both security frameworks for Java applications, used a world-readable audit.log file to record sensitive information. (CVE-2014-0059) It was found that the org.apache.catalina.servlets.DefaultServlet implementation in JBoss Web 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) 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. (CVE-2014-0119) The CVE-2014-0075 issue was discovered by David Jorm of Red Hat Product Security. All users of Red Hat JBoss Data Grid 6.2.1 as provided from the Red Hat Customer Portal are advised to upgrade to Red Hat JBoss Data Grid 6.3.0. 3. 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. 4.
