Cisco Webex Meetings and Webex Meetings Server File Redirect Vulnerability

A vulnerability in Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to redirect users to a malicious file. This vulnerability is due to improper validation of URL paths in the application interface. An attacker could exploit this vulnerability by persuading a user to follow a specially crafted URL that is designed to cause Cisco Webex Meetings to include a remote file in the web UI. A successful exploit could allow the attacker to cause the application to offer a remote file to a user, which could allow the attacker to conduct further phishing or spoofing attacks. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
