CVE-2020-3561

TITLE

Cisco Adaptive Security Appliance Software and Cisco Firepower Threat Defense Software injection vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2020-009724

DESCRIPTION

A vulnerability in the Clientless SSL VPN (WebVPN) of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to inject arbitrary HTTP headers in the responses of the affected system. The vulnerability is due to improper input sanitization. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to conduct a CRLF injection attack, adding arbitrary HTTP headers in the responses of the system and redirecting the user to arbitrary websites. The platform provides features such as highly secure access to data and network resources. Successful exploitation of this vulnerability allows attackers to exploit this vulnerability to perform CRLF injection attacks
