CVE-2019-1764

Estado: ModificadaAlta (8.8)—

A vulnerability in the web-based management interface of Session Initiation Protocol (SIP) Software for Cisco IP Phone 8800 Series could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading an authenticated user of the interface to follow a crafted link.
