This vulnerability requires physical access to the serial interface of the module or the ability to modify the system or software which uses its serial interface to send malicious AT commands.\n\n\n\n\nExploitation of the vulnerability gives full administrative (root) privileges to the attacker to execute any operating system command on TOBY-L2 which can lead to modification of the behavior of the module itself as well as the components connected with it (depending on its rights on other connected systems). It can further provide the ability to read system level files and hamper the availability of the module as well..\n\n\n\n\nThis issue affects TOBY-L2 series: TOBY-L200, TOBY-L201, TOBY-L210, TOBY-L220, TOBY-L280.\n\n"},{"lang":"es","value":"Un fallo en la validación de entrada en TOBY-L2 permite a un usuario ejecutar comandos arbitrarios del sistema operativo utilizando comandos AT específicamente manipulados. Esta vulnerabilidad requiere acceso físico a la interfaz serie del módulo o la capacidad de modificar el sistema o software que utiliza su interfaz serie para enviar comandos AT maliciosos. La explotación de la vulnerabilidad otorga privilegios administrativos (root) completos al atacante para ejecutar cualquier comando del sistema operativo en TOBY-L2, lo que puede conducir a la modificación del comportamiento del módulo en sí, así como de los componentes conectados con él (dependiendo de sus derechos en otros sistemas conectados). Además, puede proporcionar la capacidad de leer archivos a nivel del sistema y también obstaculizar la disponibilidad del módulo.
