CVE-2025-67288
Full vulnerability record from the local CVENow database.
Description
An arbitrary file upload vulnerability in Umbraco CMS v16.3.3 allows attackers to execute arbitrary code by uploading a crafted PDF file. NOTE: this is disputed by the Supplier because the responsibility for file validation (as shown in the documentation) belongs to the system administrator who is implementing Umbraco CMS in their environment, not to Umbraco CMS itself. The Supplier also states that PDF JavaScript runs in a completely isolated sandbox, not the browser's DOM context, which means that privilege boundaries would not be crossed, a related issue to CVE-2023-49279.

"value": "Una vulnerabilidad de carga arbitraria de archivos en Umbraco CMS v16.3.3 permite a los atacantes ejecutar código arbitrario mediante la carga de un archivo PDF manipulado. NOTA: esto es disputado por el Proveedor porque la responsabilidad de la validación de archivos (como se muestra en la documentación) pertenece al administrador del sistema que está implementando Umbraco CMS en su entorno, no a Umbraco CMS en sí. El Proveedor también afirma que el JavaScript de PDF se ejecuta en una sandbox completamente aislada, no en el contexto DOM del navegador, lo que significa que los límites de privilegios no se cruzarían, un problema relacionado con CVE-2023-49279."
