CVE-2015-5351

The (1) Manager and (2) Host Manager applications in Apache Tomcat 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M2 establish sessions and send CSRF tokens for arbitrary new requests, which allows remote attackers to bypass a CSRF protection mechanism by using a token.

Updated tomcat packages fix security vulnerabilities:

Directory traversal vulnerability in RequestUtil.java in Apache Tomcat 7.x before 7.0.65 allows remote authenticated users to bypass intended SecurityManager restrictions and list a parent directory via a /.. (slash dot dot) in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call, as demonstrated by the $CATALINA_BASE/webapps directory (CVE-2015-5174).

The Mapper component in 7.x before 7.0.67 processes redirects before considering security constraints and Filters, which allows remote attackers to determine the existence of a directory via a URL that lacks a trailing / (slash) character (CVE-2015-5345).

Session fixation vulnerability in Apache Tomcat 7.x before 7.0.66, when different session settings are used for deployments of multiple versions of the same web application, might allow remote attackers to hijack web sessions by leveraging use of a requestedSessionSSL field for an unintended request, related to CoyoteAdapter.java and Request.java (CVE-2015-5346).

The Manager and Host Manager applications in Apache Tomcat 7.x before 7.0.68 establish sessions and send CSRF tokens for arbitrary new requests, which allows remote attackers to bypass a CSRF protection mechanism by using a token (CVE-2015-5351).

Apache Tomcat 7.x before 7.0.68 does not place org.apache.catalina.manager.StatusManagerServlet on the org/apache/catalina/core/RestrictedServlets.properties list, which allows remote authenticated users to bypass intended SecurityManager restrictions and read arbitrary HTTP requests, and consequently discover session ID values, via a crafted web application (CVE-2016-0706).

The session-persistence implementation in Apache Tomcat 7.x before 7.0.68 mishandles session attributes, which allows remote authenticated users to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that places a crafted object in a session (CVE-2016-0714).

The setGlobalContext method in org/apache/naming/factory/ResourceLinkFactory.java in Apache Tomcat 7.x before 7.0.68 does not consider whether ResourceLinkFactory.setGlobalContext callers are authorized, which allows remote authenticated users to bypass intended SecurityManager restrictions and read or write to arbitrary application data, or cause a denial of service (application disruption), via a web application that sets a crafted global context (CVE-2016-0763).

The tomcat package has been updated to version 7.0.68 to fix these issues. The tomcat-native package has also been updated to version 1.1.34 for compatibility with the updated tomcat.

These are all security issues fixed in the tomcat-8.0.36-3.3 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the tomcat10-10.1.14-1.1 package on the GA media of openSUSE Tumbleweed.

This update for tomcat fixes the following issues:

Tomcat 8 was updated from 8.0.23 to 8.0.32, to fix bugs and security issues.

Fixed security issues:

• CVE-2015-5174: Directory traversal vulnerability in RequestUtil.java in Apache Tomcat allowed remote authenticated users to bypass intended SecurityManager restrictions and list a parent directory via a /.. (slash dot dot) in a pathname used by a web application in a getResource, getResourceAsStream, or getResourcePaths call, as demonstrated by the $CATALINA_BASE/webapps directory. (bsc#967967)
• CVE-2015-5346: Session fixation vulnerability in Apache Tomcat when different session settings are used for deployments of multiple versions of the same web application, might have allowed remote attackers to hijack web sessions by leveraging use of a requestedSessionSSL field for an unintended request, related to CoyoteAdapter.java and Request.java. (bsc#967814)
• CVE-2015-5345: The Mapper component in Apache Tomcat processes redirects before considering security constraints and Filters, which allowed remote attackers to determine the existence of a directory via a URL that lacks a trailing / (slash) character. (bsc#967965)
• CVE-2015-5351: The (1) Manager and (2) Host Manager applications in Apache Tomcat established sessions and send CSRF tokens for arbitrary new requests, which allowed remote attackers to bypass a CSRF protection mechanism by using a token. (bsc#967812)
• CVE-2016-0706: Apache Tomcat did not place org.apache.catalina.manager.StatusManagerServlet on the org/apache/catalina/core/RestrictedServlets.properties list, which allowed remote authenticated users to bypass intended SecurityManager restrictions and read arbitrary HTTP requests, and consequently discover session ID values, via a crafted web application. (bsc#967815)
• CVE-2016-0714: The session-persistence implementation in Apache Tomcat mishandled session attributes, which allowed remote authenticated users to bypass intended SecurityManager restrictions and execute arbitrary code in a privileged context via a web application that places a crafted object in a session. (bsc#967964)
• CVE-2016-0763: The setGlobalContext method in org/apache/naming/factory/ResourceLinkFactory.java in Apache Tomcat did not consider whether ResourceLinkFactory.setGlobalContext callers are authorized, which allowed remote authenticated users to bypass intended SecurityManager restrictions and read or write to arbitrary application data, or cause a denial of service (application disruption), via a web application that sets a crafted global context.
