Descriptions
Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling.
Go versiones anteriores a 1.12.10 y versiones 1.13.x anteriores a 1.13.1, permitir el Trafico No Autorizado de Peticiones HTTP.
It was discovered that net/http (through net/textproto) in golang does not correctly interpret HTTP requests where an HTTP header contains spaces before the colon. This could be abused by an attacker to smuggle HTTP requests when a proxy or a firewall is placed behind a server implemented in Go or to filter bypasses depending on the specific network configuration.
