'Name' => 'Minishare 1.4.1 Buffer Overflow',

'Description' => %q{
|
|
This is a simple buffer overflow for the minishare web
|
|
server. This flaw affects all versions prior to 1.4.2. This
|
|
is a plain stack buffer overflow that requires a "jmp esp" to reach
|
|
the payload, making this difficult to target many platforms
|
|
at once. This module has been successfully tested against
|
|
1.4.1. Version 1.3.4 and below do not seem to be vulnerable.
