"A vulnerability in the external authentication functionality of Email Security Appliance could allow an 
unauthenticated, remote attacker to bypass authentication and log in to the web management interface of an affected 
device. This vulnerability is due to improper authentication checks when an affected device uses Lightweight Directory
 Access Protocol (LDAP) for external authentication. An attacker could exploit this vulnerability by entering a 
 specific input on the login page of the affected device. A successful exploit could allow the attacker to gain 
 unauthorized access to the web-based management interface of the affected device.
