Description

Tomcat (6, 7, 8) packages provided by default repositories on Debian-based
distributions (including Debian, Ubuntu etc.) provide a vulnerable
tomcat init script that allows local attackers who have already gained access
to the tomcat account (for example, by exploiting an RCE vulnerability
in a java web application hosted on Tomcat, uploading a webshell etc.) to
escalate their privileges from tomcat user to root and fully compromise the
target system.

Tested against Tomcat 8.0.32-1ubuntu1.1 on Ubuntu 16.04
