Description
This module exploits a command injection vulnerability against Dovecot with Exim using the "use_shell" option. It uses the sender's address to inject arbitrary commands, since this is one of the user-controlled variables. It has been successfully tested on Debian Squeeze using the default Exim4 with the dovecot-common packages.
