An attacker could exploit this vulnerability by sending crafted HTTPS requests to the AP file upload interface. A successful exploit could allow the attacker to upload files, perform path traversal, and execute arbitrary commands with root privileges."}, {"lang": "es", "value": "Una vulnerabilidad en la funci\u00f3n de descarga de im\u00e1genes de puntos de acceso (AP) fuera de banda del software Cisco IOS XE para controladores de LAN inal\u00e1mbrica (WLC) podr\u00eda permitir que un atacante remoto no autenticado cargue archivos arbitrarios en un sistema afectado. Esta vulnerabilidad se debe a la presencia de un token web JSON (JWT) codificado de forma r\u00edgida en un sistema afectado. Un atacante podr\u00eda explotar esta vulnerabilidad enviando solicitudes HTTPS manipuladas a la interfaz de descarga de im\u00e1genes del AP.
