Descriptions

Dropbox Desktop Folder Sharing Mark-of-the-Web Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of Dropbox Desktop. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the handling of shared folders. When syncing files from a shared folder belonging to an untrusted account, the Dropbox desktop application does not apply the Mark-of-the-Web to the local files. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user. Was ZDI-CAN-23991.

Vulnerabilidad de omisión de la marca de la web para compartir carpetas de Dropbox Desktop. Esta vulnerabilidad permite a atacantes remotos eludir el mecanismo de protección de la Marca Web en las instalaciones afectadas de Dropbox Desktop. Se requiere la interacción del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica existe en el manejo de carpetas compartidas. Al sincronizar archivos desde una carpeta compartida que pertenece a una cuenta que no es de confianza, la aplicación de escritorio de Dropbox no aplica la Marca de la Web a los archivos locales. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código arbitrario en el contexto del usuario actual. Era ZDI-CAN-23991.
