TITLE

Cisco Adaptive Security Appliance Software  and  Cisco Firepower Threat Defense Software  In  HTTP  Request Smuggling Vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2021-017803

DESCRIPTION

A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition. This vulnerability is due to improper input validation when parsing HTTPS requests. An attacker could exploit this vulnerability by sending a malicious HTTPS request to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. The platform provides features such as highly secure access to data and network resources
