New Cisco firewall zero-day exploited to crash SSL VPN devices

Summary written by editorial AI · Source link below
Cisco released security updates to patch a denial-of-service zero-day in Adaptive Security Appliance (ASA) and Threat Defense (FTD) software that attackers are exploiting to remotely crash vulnerable firewall devices. [...]
Editorial Analysis
SSL VPN is the remote-access lifeline for most enterprises; a DoS zero-day that crashes these devices can halt distributed workforces and expose fallback connections to interception.
Apply the Cisco ASA/FTD patch immediately, verify VPN failover capabilities, and investigate any recent unexplained appliance reboots.
An actively exploited Cisco firewall zero-day can crash enterprise VPN infrastructure—immediate patching is required.
