CVE-2020-3361

A vulnerability in Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to gain unauthorized access to a vulnerable Webex site. The vulnerability is due to improper handling of authentication tokens by a vulnerable Webex site. An attacker could exploit this vulnerability by sending crafted requests to a vulnerable Cisco Webex Meetings or Cisco Webex Meetings Server site. If successful, the attacker could gain the privileges of another user within the affected Webex site.
