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.
