CVE-2019-1866— Cisco Webex Business Suite 数据伪造问题漏洞

Cisco Webex Business Suite Host Header Value Integrity Vulnerability

Cisco Webex Business Suite before 39.1.0 contains a vulnerability that could allow an unauthenticated, remote attacker to affect the integrity of the application. The vulnerability is due to improper validation of host header values. An attacker with a privileged network position, either a man-in-the-middle or by intercepting wireless network traffic, could exploit this vulnerability to manipulate header values sent by a client to the affected application. The attacker could cause the application to use input from the header to redirect a user from the Cisco Webex Meetings Online site to an arbitrary site of the attacker's choosing.
