The application does not account for symlinks placed inside the sandbox directory, which can be leveraged by an attacker to write to arbitrary files and gain code execution outside of the sandbox. When executing a submission, Judge0 writes a `run_script` to the sandbox directory. The security issue is that an attacker can create a symbolic link (symlink) at the path `run_script` before this code is executed, resulting in the `f.write` writing to an arbitrary file on the unsandboxed system. An attacker can leverage this vulnerability to overwrite scripts on the system and gain code execution outside of the sandbox.\n"}, {"lang": "es", "value": "Judge0 es un sistema de ejecuci\u00f3n de c\u00f3digo en l\u00ednea de c\u00f3digo abierto. La aplicaci\u00f3n no tiene en cuenta los enlaces simb\u00f3licos colocados dentro del directorio de la zona de pruebas, que un atacante puede aprovechar para escribir en archivos arbitrarios y obtener la ejecuci\u00f3n de c\u00f3digo fuera de la zona de pruebas. Al ejecutar un env\u00edo, Judge0 escribe un `run_script` en el directorio sandbox. El problema de seguridad es que un atacante puede crear un enlace simb\u00f3lico (enlace simb\u00f3lico) en la ruta `run_script` antes de que se ejecute este c\u00f3digo, lo que da como resultado que `f.write` escriba en un archivo arbitrario en el sistema sin espacio aislado.
