This module enumerates Apache Tomcat's usernames via malformed requests to
|
|
j_security_check, which can be found in the web administration package. It should
|
|
work against Tomcat servers 4.1.0 - 4.1.39, 5.5.0 - 5.5.27, and 6.0.0 - 6.0.18.
|
|
Newer versions no longer have the "admin" package by default. The 'admin' package
|
|
is no longer provided for Tomcat 6 and later versions.

If your Tomcat doesn't have the admin package by default, download it here:
|
|
http://archive.apache.org/dist/tomcat/
|
|
|
|
The package name should look something like: apache-tomcat-[version]-admin.zip
