Default credentials

The most interesting path of Tomcat is /manager/html, inside that path you can upload and deploy war files (execute code). But this path is protected by basic HTTP auth, the most common credentials are:

admin:admin
tomcat:tomcat
admin:<NOTHING>
admin:s3cr3t
tomcat:s3cr3t
admin:tomcat

/examples

The following example scripts that come with Apache Tomcat v4.x - v7.x and can be used by attackers to gain information about the system. These scripts are also known to be vulnerable to cross site scripting (XSS) injection (from herearrow-up-right).

Path Traversal (..;/)

In some vulnerable configurations of Tomcat you can gain access to protected directories in Tomcat using the path: /..;/

So, for example, you might be able to access the Tomcat manager page by accessing: www.vulnerable.com/lalala/..;/manager/html

Another way to bypass protected paths using this trick is to access http://www.vulnerable.com/;param=value/manager/html

RCE through .WAR

Finally, if you have access to the Tomcat Web Application Manager, you can upload and deploy a .war file (execute code).
