CVE-2025-63680
Full vulnerability record from the local CVENow database.
Description
Nero BackItUp in the Nero Productline is vulnerable to a path parsing/UI rendering flaw (CWE-22) that, in combination with Windows ShellExecuteW fallback extension resolution, leads to arbitrary code execution when a user clicks a crafted entry. By creating a trailing-dot folder and placing a same-basename script, Nero BackItUp renders the file as a folder icon and then invokes ShellExecuteW, which executes the script via PATHEXT fallback (.COM/.EXE/.BAT/.CMD). The issue affects recent Nero BackItUp product lines (2019-2025 and earlier) and has been acknowledged by the vendor.

"value": "Nero BackItUp en la línea de productos Nero es vulnerable a un fallo de análisis de ruta/renderizado de interfaz de usuario (CWE-22) que, en combinación con la resolución de extensión de reserva de Windows ShellExecuteW, conduce a la ejecución de código arbitrario cuando un usuario hace clic en una entrada diseñada. Al crear una carpeta con un punto final y colocar un script con el mismo nombre base, Nero BackItUp renderiza el archivo como un icono de carpeta y luego invoca ShellExecuteW, que ejecuta el script a través de la reserva PATHEXT (.COM/.EXE/.BAT/.CMD). El problema afecta a las líneas de productos recientes de Nero BackItUp (2019-2025 y anteriores) y ha sido reconocido por el proveedor."
