CVE-2025-49007

Rack is a modular Ruby web server interface. Starting in version 3.1.0 and prior to version 3.1.16, there is a denial of service vulnerability in the Content-Disposition parsing component of Rack. This is very similar to the previous security issue CVE-2022-44571. Carefully crafted input can cause Content-Disposition header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. This header is used typically used in multipart parsing. Any applications that parse multipart posts using Rack (virtually all Rails applications) are impacted. Version 3.1.16 contains a patch for the vulnerability.

Summary		(es) Rack es una interfaz modular de servidor web Ruby. A partir de la versión 3.1.0 y anteriores a la 3.1.16, existe una vulnerabilidad de denegación de servicio en el componente de análisis Content-Disposition de Rack. Esto es muy similar al problema de seguridad anterior CVE-2022-44571. Una entrada cuidadosamente manipulada puede provocar que el análisis del encabezado Content-Disposition en Rack tarde un tiempo inesperado, lo que podría resultar en un vector de ataque de denegación de servicio. Este encabezado se usa habitualmente en el análisis multiparte. Cualquier aplicación que analice entradas multiparte con Rack (prácticamente todas las aplicaciones Rails) se ve afectada. La versión 3.1.16 incluye un parche para esta vulnerabilidad.
