Description

A vulnerability in the client isolation mechanism may allow an attacker to bypass Layer 2 (L2) communication restrictions between clients and redirect traffic at Layer 3 (L3). In addition to bypassing policy enforcement, successful exploitation - when combined with a port-stealing attack - may enable a bi-directional Machine-in-the-Middle (MitM) attack.
