ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file. (A configuration file that provides a complete literal username is not categorized as an untrusted source.)

ssh en OpenSSH antes de la versión 10.1 permite caracteres de control en nombres de usuario que se originan de ciertas fuentes posiblemente no confiables, lo que podría llevar a la ejecución de código cuando se utiliza un ProxyCommand. Las fuentes no confiables son la línea de comandos y la expansión de secuencias con % de un archivo de configuración. (Un archivo de configuración que proporciona un nombre de usuario literal completo no se clasifica como una fuente no confiable).
