Descriptions

Apache HTTP Server versions 2.4.6 to 2.4.46 mod_proxy_wstunnel configured on an URL that is not necessarily Upgraded by the origin server was tunneling the whole connection regardless, thus allowing for subsequent requests on the same connection to pass through with no HTTP validation, authentication or authorization possibly configured.

Apache HTTP Server versiones 2.4.6 a 2.4.46 la función mod_proxy_wstunnel configurado en una URL que no es necesariamente Actualizada por el servidor de origen estaba tunelizando toda la conexión a pesar de ello, permitiendo así para las peticiones posteriores en la misma conexión pasar sin comprobación HTTP, autenticación o autorización posiblemente configurada

A flaw was found in Apache httpd. The mod_proxy_wstunnel module tunnels non-upgraded connections.
