TITLE

Apache Tomcat Security restriction bypass vulnerability

DESCRIPTION

The error page mechanism of the Java Servlet Specification requires that, when an error occurs and an error page is configured for the error that occurred, the original request and response are forwarded to the error page. This means that the request is presented to the error page with the original HTTP method. If the error page is a static file, expected behaviour is to serve content of the file as if processing a GET request, regardless of the actual HTTP method. The Default Servlet in Apache Tomcat 9.0.0.M1 to 9.0.0.M20, 8.5.0 to 8.5.14, 8.0.0.RC1 to 8.0.43 and 7.0.0 to 7.0.77 did not do this. Depending on the original request this could lead to unexpected and undesirable results for static error pages including, if the DefaultServlet is configured to permit writes, the replacement or removal of the custom error page. Notes for other user provided error pages: (1) Unless explicitly coded otherwise, JSPs ignore the HTTP method. JSPs used as error pages must must ensure that they handle any error dispatch as a GET request, regardless of the actual method. (2) By default, the response generated by a Servlet does depend on the HTTP method. Custom Servlets used as error pages must ensure that they handle any error dispatch as a GET request, regardless of the actual method. Apache Tomcat Contains a security restriction bypass vulnerability. The Apache Software Foundation From Apache Tomcat An update has been released for the following vulnerabilities: * * Security restriction bypass vulnerability related to error page processing (CVE-2017-5664 )Crafted HTTP By processing the request, the error page may be deleted or overwritten. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may lead to further attacks. ========================================================================== Ubuntu Security Notice USN-3519-1 January 08, 2018 tomcat7, tomcat8 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Several security issues were fixed in Tomcat. A remote attacker could use this issue to obtain wrong responses possibly containing sensitive information. (CVE-2017-5664) It was discovered that Tomcat incorrectly handled the CORS filter. (CVE-2017-7674) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.04: libtomcat8-java 8.0.38-2ubuntu2.2 tomcat8 8.0.38-2ubuntu2.2 Ubuntu 16.04 LTS: libtomcat8-java 8.0.32-1ubuntu1.5 tomcat8 8.0.32-1ubuntu1.5 Ubuntu 14.04 LTS: libtomcat7-java 7.0.52-1ubuntu0.13 tomcat7 7.0.52-1ubuntu0.13 In general, a standard system update will make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss Web Server 2 security update Advisory ID: RHSA-2017:2493-01 Product: Red Hat JBoss Web Server Advisory URL: https://access.redhat.com/errata/RHSA-2017:2493 Issue date: 2017-08-21 CVE Names: CVE-2016-6304 CVE-2016-8610 CVE-2017-5647 CVE-2017-5664 ===================================================================== 1. Summary: An update is now available for Red Hat JBoss Enterprise Web Server 2.1.2 for Red Hat Enterprise Linux 6 and Red Hat JBoss Enterprise Web Server 2.1.2 for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. 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. 2. Relevant releases/architectures: Red Hat JBoss Enterprise Web Server 2 for RHEL 6 Server - i386, noarch, x86_64 Red Hat JBoss Enterprise Web Server 2 for RHEL 7 Server - noarch, x86_64 3. Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library. This release provides an update to OpenSSL and Tomcat 6/7 for Red Hat JBoss Web Server 2.1.2. The updates are documented in the Release Notes document linked to in the References. Users of Red Hat JBoss Web Server 2.1.2 should upgrade to these updated packages, which resolve several security issues. Security Fix(es): * A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. (CVE-2016-6304) * A vulnerability was discovered in tomcat's handling of pipelined requests when "Sendfile" was used. If sendfile processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5664) * A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients. (CVE-2016-8610) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-6304 and Shi Lei (Gear Team of Qihoo 360 Inc.) for reporting CVE-2016-8610. Upstream acknowledges Shi Lei (Gear Team of Qihoo 360 Inc.) as the original reporter of CVE-2016-6304. 4. Solution: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. After installing the updated packages, the httpd daemon will be restarted automatically. 5.

Security Fix(es): * It was found that when using remote logging with log4j socket server the log4j server would deserialize any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log event that, during deserialization, would execute arbitrary code in the context of the logger application. When running an untrusted application under a SecurityManager it was possible, under some circumstances, for that application to retain references to the request or response objects and thereby access and/or modify information associated with another web application.

(CVE-2017-5664) * Two vulnerabilities were discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution.
