  Sygate Enforcer Unauthenticated Broadcast Bypassing
------------------------------------------------------------------------

SUMMARY

 <http://www.sygate.com/products/universal_enforcement.htm> Sygate
Enforcers are described as "network gateway devices that enforce host
integrity at network access points". Architecturally they function as an
authenticated, packet-filtering firewall device. The Enforcer interacts
with the Sygate Security Agent (SAA [the personal firewall component])
product and limits access to protected networks/hosts to authenticated
clients that comply with a predefined policy.

In practice, the Enforcer does not limit broadcast traffic (both local-net
and all-nets) from passing through prior to authentication, allowing hosts
that are protected by the Enforcer to still be attacked.

DETAILS

Vulnerable Systems:
 * Sygate Enforcer version prior to 3.5MR1

CVE Information:
 <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0593>
CAN-2004-0593
