Severity ?
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
Summary
Gunicorn fails to properly validate Transfer-Encoding headers, leading to HTTP Request Smuggling (HRS) vulnerabilities. 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.

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. Esta vulnerabilidad permite una variedad de ataques que incluyen envenenamiento de cach\u00e9, manipulaci\u00f3n de sesiones y exposici\u00f3n de datos."
