Cisco Webex Meetings Cross-Site Scripting Vulnerability

A vulnerability in the user profile component of Cisco Webex Meetings could have allowed an authenticated, remote attacker with low privileges to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed. This vulnerability existed because of insufficient validation of user-supplied input to the user profile component of Cisco Webex Meetings. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could have allowed the attacker to conduct an XSS attack against the targeted user. As mentioned, Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is necessary to update on-premises software or devices. There are no workarounds that address this vulnerability.
