By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue is due to Gunicorn's handling of Transfer-Encoding headers, where it incorrectly processes requests with multiple, conflicting Transfer-Encoding headers, treating them as chunked regardless of the final encoding specified. This vulnerability allows for a range of attacks including cache poisoning, session manipulation, and data exposure."}, {"lang": "es", "value": "Gunicorn no puede validar correctamente los encabezados Transfer-Encoding, lo que genera vulnerabilidades de contrabando de solicitudes HTTP (HRS). Al manipular solicitudes con encabezados Transfer-Encoding conflictivos, los atacantes pueden eludir las restricciones de seguridad y acceder a endpoints restringidos. Este problema se debe al manejo que hace Gunicorn de los encabezados Transfer-Encoding, donde procesa incorrectamente solicitudes con m\u00faltiples encabezados Transfer-Encoding conflictivos, trat\u00e1ndolos como fragmentados independientemente de la codificaci\u00f3n final especificada.
