Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software WebVPN CPU Denial of Service Vulnerability

view advisory published 2019-10-02

A vulnerability in the WebVPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause increased CPU utilization on an affected device. The vulnerability is due to excessive processing load for a specific WebVPN HTTP page request. An attacker could exploit this vulnerability by sending multiple WebVPN HTTP page load requests for a specific URL. A successful exploit could allow the attacker to increase CPU load on the device, resulting in a denial of service (DoS) condition, which could cause traffic to be delayed through the device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
