A vulnerability in the Virtual Keyboard Video Monitor (vKVM) connection handling of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to redirect a user to a malicious website. This vulnerability is due to insufficient verification of vKVM endpoints. An attacker could exploit this vulnerability by persuading a user to click a crafted link.
