Description

According to its self-reported version, Cisco Webex Meetings is prior to 39.7.0. It is, therefore, affected by a privilege escalation vulnerability in its Network Recording Admin page due to insufficient access control validation. An authenticated, remote attacker could exploit this, by issuing crafted HTTP requests, to view or delete recordings which they would normally not be permitted to access.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

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