Multiple Cogent products are vulnerable to a denial of service, caused by a NULL pointer dereference when handling formatted text commands. By sending a specially-crafted command containing a backslash to TCP ports 4502 or 4503, a remote attacker could exploit this vulnerability to cause the application to crash.
