could allow an authenticated, remote attacker to discover confidential information about the appliances that
should be available only to an administrative user.");

information at rest in response to Simple Network Management Protocol (SNMP) poll requests. An attacker could
exploit this vulnerability by doing a crafted SNMP poll request to the targeted security appliance.");

should be restricted, and the attacker could use this information to conduct additional reconnaissance. The
attacker must know the configured SNMP community string to exploit this vulnerability.");
