Descriptions

Discord-Recon is a bot for the Discord chat service. Versions of Discord-Recon 0.0.3 and prior contain a vulnerability in which a remote attacker is able to overwrite any file on the system with the command results. This can result in remote code execution when the user overwrite important files on the system. As a workaround, bot maintainers can edit their `setting.py` file then add `<` and `>` into the `RCE` variable inside of it to fix the issue without an update. The vulnerability is patched in version 0.0.4.

Discord-Recon es un bot para el servicio de chat Discord. Unas versiones de Discord-Recon versiones 0.0.3 y anteriores, contienen una vulnerabilidad en la que un atacante remoto puede sobrescribir cualquier archivo del sistema con los resultados del comando. Esto puede resultar en la ejecución de código remota cuando el usuario sobrescribe archivos importantes en el sistema. Como solución alternativa, los encargados de mantenimiento de bots pueden editar su archivo "setting.py" y luego agregar" ("y") "en la variable" RCE" dentro de él para solucionar el problema sin una actualización. La vulnerabilidad está parcheada en la versión 0.0.4
