  script_tag(name:"insight", value:"ResourceLinkFactory.setGlobalContext() is a public method and was discovered to be accessible by web applications running under a security manager without any checks. This allowed a malicious web application to inject a malicious global context that could in turn be used to disrupt other web applications and/or read and write data owned by other web applications. (CVE-2016-0763)

A session fixation vulnerability was discovered that might allow remote attackers to hijack web sessions by leveraging use of a requestedSessionSSL field for an unintended request when different session settings are used for deployments of multiple versions of the same web application. (CVE-2015-5346)

The Manager and Host Manager applications were discovered to 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)

The session-persistence implementation was discovered to mishandle 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)

It was discovered that org.apache.catalina.manager.StatusManagerServlet was not placed 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.
