"A vulnerability in the messaging interface of Cisco Webex App, formerly Webex Teams, could allow an unauthenticated,
remote attacker to manipulate links or other content within the messaging interface. This vulnerability exists because
the affected software does not properly handle character rendering. An attacker could exploit this vulnerability by
sending messages within the application interface. A successful exploit could allow the attacker to modify the display
of links or other content within the interface, potentially allowing the attacker to conduct phishing or spoofing
attacks.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version   
number.");
