Description
This module exploits the Shellshock vulnerability, a flaw in how the Bash shell handles external environment variables. This module targets the Pure-FTPd FTP server when it has been compiled with the --with-extauth flag and an external Bash script is used for authentication. If the server is not set up this way, the exploit will fail, even if the version of Bash in use is vulnerable.
