The vulnerability is due to the lack of a proper locking mechanism on critical variables that need to stay static until used. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a set of RPM-related CLI commands. A successful exploit could allow the attacker to perform arbitrary command injection. The attacker would need administrator credentials for the targeted device."}, {"lang": "es", "value": "Una vulnerabilidad en el subsistema Remote Package Manager (RPM) del software NX-OS de Cisco podr\u00eda permitir que un atacante local autorizado con credenciales de administrador explote una condici\u00f3n de carrera de tiempo de comprobaci\u00f3n (TOCTOU) para corromper las variables locales , lo que podr\u00eda dar lugar a una inyecci\u00f3n de mando arbitraria. La vulnerabilidad se debe a la falta de un mecanismo de bloqueo adecuado en las variables cr\u00edticas que deben permanecer est\u00e1ticas hasta su uso.
