EPSS · scored 2026-10-27

A vulnerability in the SOAP API of Cisco Expressway Series and Cisco TelePresence Video Communication Server could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. This vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected system. An attacker could exploit this vulnerability by persuading a user of the REST API to follow a crafted link. A successful exploit could allow the attacker to cause the affected system to reload.
