In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name.
En ssh en OpenSSH anterior a 9.6, la inyección de comandos del sistema operativo puede ocurrir si un nombre de usuario o nombre de host tiene metacaracteres de shell, y un token de expansión hace referencia a este nombre en ciertas situaciones. Por ejemplo, un repositorio Git que no es de confianza puede tener un submódulo con metacaracteres de shell en un nombre de usuario o nombre de host.
