An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack.

Se detectó un problema en Ruby versiones hasta 2.5.8, versiones 2.6.x hasta 2.6.6 y versiones 2.7.x hasta 2.7.1. WEBrick, un simple servidor HTTP integrado con Ruby, no había comprobado rigurosamente el valor del encabezado transfer-encoding. Un atacante puede explotar potencialmente este problema para omitir un proxy inverso (que también presenta una comprobación de encabezado deficiente), que puede conllevar a un ataque de Trafico Inapropiado de Peticiones HTTP
