From 2.2.0 until 2.7.3, the inline query parameter on browsable-share file downloads and authenticated user-file downloads suppresses Content-Disposition: attachment, allowing an attacker-controlled HTML file stored in a share or home directory to be served as text/html in the SFTPGo web origin. An attacker who can place the file can send a crafted link to a victim, and opening that link executes the stored content in the victim's browser context. Exploitation requires social engineering and suitable share or shared-folder access, while HttpOnly session cookies limit direct cookie theft. This issue is fixed in version 2.7.3."},{"lang":"es","value":"SFTPGo es una solución de transferencia de archivos de código abierto y basada en eventos. Desde la versión 2.2.0 hasta la 2.7.3, el parámetro de consulta inline en las descargas de archivos de recursos compartidos navegables y en las descargas de archivos de usuarios autenticados suprime Content-Disposition: attachment, permitiendo que un archivo HTML controlado por el atacante almacenado en un recurso compartido o directorio personal sea servido como text/html en el origen web de SFTPGo. Un atacante que puede colocar el archivo puede enviar un enlace malicioso a una víctima, y al abrir ese enlace se ejecuta el contenido almacenado en el contexto del navegador de la víctima.
