WPA/WPA2 Vulnerability Mitigation
Until the vSZ-H patch code for release 3.4 is available, the CVE-2017-13082 PTK Reinstallation Vulnerability can be mitigated by ensuring
802.11r is disabled on any SSID/WLAN and that Mesh is disabled on any AP.
By default, 802.11r and Mesh are disabled. Your network is safe from attack, there is nothing required to be done if those defaults are intact.
Otherwise, to mitigate CVE-2017-13082 PTK Reinstallation Vulnerability, follow the instructions to disable 802.11r (on SSID/WLAN) and Mesh
(on AP).

Mesh
Verify that Mesh is not enabled for your vSZ-H network (this is the default setting). Navigate to your AP Zone by selecting Configuration> AP
Zones> (Your AP Zone Name). In the General Information area, if Mesh is disabled, no further action is needed.

Figure 1: Mesh vSZ-H
If Mesh is enabled, it cannot be disabled for the system. However, the APs can have Mesh disabled. You should only do this if they are not
participating in a Mesh link connection or you risk isolating any non-wired AP. To disable Mesh on each AP, select Configuration> Access
Points> Edit for each access point then Disable Mesh and save your changes.

802.11r (Fast Roaming)
The Fast BSS Transition (802.11r) feature is found under each Wi-Fi Network (WLAN) configured. This feature is disabled by default. To verify
that 11r is not enabled for your WLAN, navigate to Configuration> AP Zones> (Your AP Zone)> (Your WLAN Name).

Figure 3: 802.11r vSZ-H

Select your WLAN; if the Enable 802.11r Fast BSS Transition check box is not selected, no further action is needed. If it is, deselect it and save
your changes.
