Summary

A vulnerability in the Webex Network Recording Admin page of Cisco Webex Meetings could allow an authenticated, remote attacker to elevate privileges in the context of the affected page. To exploit this vulnerability, the attacker must be logged in as a low-level administrator. The vulnerability is due to insufficient access control validation. An attacker could exploit this vulnerability by submitting a crafted URL request to gain privileged access in the context of the affected page. A successful exploit could allow the attacker to elevate privileges in the Webex Recording Admin page, which could allow them to view or delete recordings that they would not normally be able to access.

descriptionAccording 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.
