- 漏洞描述

Nortel Contivity VPN clients contain a flaw that maw allow a remote attacker to gain access to a gateway. The issue is due to the client not properly checking the gateway certificate before the user is prompted with a dialog box. While the dialog box is being displayed, the VPN tunnel remains open potentially allowing for a man-in-the-middle attack allowing access to an arbitrary gateway.
