Description
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. A successful exploit could allow the attacker to redirect a user to a malicious webpage and potentially capture user credentials. Note: The affected vKVM client is also included in Cisco UCS Manager.
