This module will download a file of your choice against Symantec Messaging
|

Gateway. This is possible by exploiting a directory traversal vulnerability
|
|
when handling the 'logFile' parameter, which will load an arbitrary file as
|
|
an attachment. Note that authentication is required in order to successfully
|
|
download your file.
