Apache Tomcat examples directory vulnerabilities

Description

Apache Tomcat default installation contains the "/examples" directory which has many example servlets and JSPs. Some of these examples are a security risk and should not be deployed on a production server.
The Sessions Example servlet (installed at /examples/servlets/servlet/SessionExample) allows session manipulation. Because the session is global this servlet poses a big security risk as an attacker can potentitally become an administrator by manipulating its session.

Impact
Bypassing HttpOnly Cookies protection, CSRF cookies manipulation, Session manipulation.

Recommendation
Disable public access to the examples directory.
