Description
A vulnerability in the authentication component of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the authentication component of Cisco Webex Meetings.
