      "value": "A vulnerability in the CLI of Cisco ASR 5000 Series Aggregated Services Routers running the Cisco StarOS operating system could allow an authenticated, local attacker to bypass the CLI restrictions and execute commands on the underlying operating system. The vulnerability is due to insufficient input sanitization of user-supplied input at the CLI. An attacker could exploit this vulnerability by crafting a script on the device that will allow them to bypass built-in restrictions. An exploit could allow the unauthorized user to launch the CLI directly from a command shell. Cisco Bug IDs: CSCvd47722. Known Affected Releases: 21.0.v0.65839."

Esta vulnerabilidad se debe a la insuficiente sanitización de las entradas proporcionadas por el usuario en el CLI. Un atacante podría explotar esta vulnerabilidad creando un script en el dispositivo que les permitirá omitir las restricciones incorporadas. Un exploit podría permitir que el usuario sin autorización lance el CLI directamente desde una consola de comandos. Cisco Bug IDs: CSCvd47722. Versiones afectadas conocidas: 21.0.v0.65839."
