      "value": "Backdrop CMS 1.12.x before 1.12.8 and 1.13.x before 1.13.3 allows the upload of entire-site configuration archives through the user interface or command line. It does not sufficiently check uploaded archives for invalid data, potentially allowing non-configuration scripts to be uploaded to the server. (This attack is mitigated by the attacker needing the \"Synchronize, import, and export configuration\" permission, a permission that only trusted administrators should be given. Other preventative measures in Backdrop CMS prevent the execution of PHP scripts, so another server-side scripting language must be accessible on the server to execute code.) Note: This has been disputed by multiple 3rd parties due to advanced permissions that are needed to exploit."

No comprueba suficientemente los archivos cargados en busca de datos no válidos, lo que potencialmente permite que los scripts que no sean de configuración sean cargados en el servidor. (Este ataque es mitigado por el atacante necesitando el permiso \"Synchronize, import, and export configuration\", que solo deben ser otorgados a administradores confiables. Otras medidas preventivas en CMS de Backdrop impiden la ejecución de scripts de PHP, entonces otro lenguaje de script del lado del servidor debe estar accesible en el servidor para ejecutar el código)."
