Descriptions

An issue was discovered in Backdrop CMS 1.13.x before 1.13.5 and 1.14.x before 1.14.2. It 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, allowing non-configuration scripts to potentially be uploaded to the server. This issue is mitigated by the fact that the attacker would be required to have the "Synchronize, import, and export configuration" permission, a permission that only trusted administrators should be given. Other measures in the product prevent the execution of PHP scripts, so another server-side scripting language must be accessible on the server to execute code.

Se detectó un problema en Backdrop CMS versiones 1.13.x anteriores a 1.13.5 y versiones 1.14.x anteriores a 1.14.2. Permite cargar archivos de configuración de todo el sitio por medio de la interfaz de usuario o la línea de comandos. No comprueba suficientemente los archivos cargados en busca de datos no válidos, permitiendo que los scripts que no sean de configuración sean cargados potencialmente en el servidor. Este problema es mitigado por el hecho de que el atacante debería tener el permiso "Synchronize, import, and export configuration", un permiso que solo debería ser otorgado por los administradores de confianza. Otras medidas en el producto evitan la ejecución de scripts PHP, por lo que otro lenguaje de scripting del lado del servidor debe estar accesible en el servidor para ejecutar el código.
