An attacker could exploit this vulnerability by injecting malicious code into a specific data field in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have valid user credentials with privileges that allow for vKVM access on the affected device.\r\nNote: The affected vKVM client is also included in Cisco UCS Manager."}, {"lang": "es", "value": "Una vulnerabilidad en la gesti\u00f3n de la conexi\u00f3n de Virtual Keyboard Video Monitor (vKVM) de Cisco Integrated Management Controller (IMC) podr\u00eda permitir que un atacante remoto autenticado con privilegios bajos realice un ataque de cross-site scripting (XSS) almacenado contra un usuario de la interfaz. Esta vulnerabilidad se debe a una validaci\u00f3n insuficiente de la entrada proporcionada por el usuario por la interfaz de administraci\u00f3n web de un sistema afectado.
