## Description

Command injection vulnerabilities typically occur when data enters the application from an untrusted source, the data is part of a string that is executed as a command by the application, and the execution of the command allows the attacker to execute commands that they would not normally be able to execute.

## Prevention

## Consequences

- Ejecutar comandos no autorizados
- Leer datos de la aplicación
- Modificar datos de la aplicación
- DoS

## Mitigations

- Usa llamadas de biblioteca en lugar de procesos externos para recrear la funcionalidad deseada
- Ejecuta el código en un entorno sandbox que imponga límites estrictos
- Usa una biblioteca o framework verificado que no permita esta debilidad
