If you have a Cisco Firewall and haven’t upgraded after Feb, 7th 2016 and have any crypto on the outside interfaces then you are vulnerable.

Cisco has published a CRITICAL vulnerability on their Cisco ASA firewalls.  This vulnerability is on any ASA with a VPN setup on it.  The fix is to upgrade to the latest firmware 9.1.7.

This vulnerability directly impacts many of you!  Please read the following Cisco Security Advisory:

Hackers are using this attack now that it has been published:

Each upgrade will take time as the automated upgrades typically break the VPNs.

Again, to fix this vulnerability upgrade to the latest patch firmware 9.1.7 – if you need assistance email PEI at or call (303) 823-4321.
