      "value": "Microsoft UFO open-source framework for intelligent automation across devices and platforms. Microsoft UFO tagged releases up to and including v3.0.0 contain an OS command injection vulnerability in the shell action replay path. In affected releases, ShellReceiver.run_shell() passes a command string from action parameters directly to subprocess.Popen() with shell=True and executable=powershell.exe. The same shell-execution behavior is also reachable through ShellReceiver.execute_command(). The shell receiver is invoked by action classes such as RunShellCommand.execute() and ExecuteCommand.execute(), which forward stored action parameters to the shell receiver. Because UFO stores planned and executed actions in per-session JSON records, an attacker who can write or modify a session/action JSON file can plant a shell action. When the session is resumed or replayed, UFO executes the attacker's command as the UFO process user."

      "value": "Microsoft UFO, un framework de código abierto para automatización inteligente en todos los dispositivos y plataformas. Las versiones etiquetadas de Microsoft UFO hasta e incluyendo la v3.0.0 contienen una vulnerabilidad de inyección de comandos del sistema operativo en la ruta de repetición de acciones de shell. En las versiones afectadas, ShellReceiver.run_shell() pasa una cadena de comandos de los parámetros de acción directamente a subprocess.Popen() con shell=True y executable=powershell.exe. El mismo comportamiento de ejecución de shell también es alcanzable a través de ShellReceiver.execute_command(). El receptor de shell es invocado por clases de acción como RunShellCommand.execute() y ExecuteCommand.execute(), que reenvían los parámetros de acción almacenados al receptor de shell. Debido a que UFO almacena acciones planificadas y ejecutadas en registros JSON por sesión, un atacante que puede escribir o modificar un archivo JSON de sesión/acción puede plantar una acción de shell. Cuando la sesión se reanuda o se reproduce, UFO ejecuta el comando del atacante como el usuario del proceso de UFO."
