The attacker must authenticate with valid user credentials. The vulnerability is due to the incorrect implementation of a Bash shell command that allows role-based access control (RBAC) to be bypassed. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Bash prompt. A successful exploit could allow the attacker to escalate their privilege level by executing commands that should be restricted to other roles. For example, a dev-ops user could escalate their privilege level to admin with a successful exploit of this vulnerability."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n shell \"Bash\" del software Cisco NX-OS podr\u00eda permitir a un atacante local autenticado para escalar su nivel de privilegios ejecutando comandos autorizados a otros roles de usuario.
