Apache Tomcat User Enumeration



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.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/scanner/http/tomcat_enum
msf auxiliary(tomcat_enum) > show actions
msf auxiliary(tomcat_enum) > set ACTION < action-name >
msf auxiliary(tomcat_enum) > show options
    ...show and set options...
msf auxiliary(tomcat_enum) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
