According to its self-reported version, Cisco Webex Meetings is affected by a vulnerability in the scheduled meeting template feature due to insufficient authorization enforcement for the creation of scheduled meeting templates. An authenticated, remote attacker can exploit this, by sending a crafted request to the Webex Meetings interface, in order to create a scheduled meeting template that would belong to another user in their organization.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
