Descriptions

An issue was discovered in Varnish Cache 7.x before 7.1.2 and 7.2.x before 7.2.1. A request smuggling attack can be performed on Varnish Cache servers by requesting that certain headers are made hop-by-hop, preventing the Varnish Cache servers from forwarding critical headers to the backend.

Se descubrió un problema en Varnish Cache 7.x anterior a la versión 7.1.2 y 7.2.x anterior a la versión 7.2.1. Se puede realizar un ataque de tráfico ilegal de solicitudes en los servidores Varnish Cache solicitando que ciertos encabezados se realicen salto por salto, evitando que los servidores Varnish Cache reenvíen encabezados críticos al backend.

An update that fixes two vulnerabilities is now available. This update for varnish fixes the following issues. Fixed a HTTP request smuggling via hop-by-hop headers. Fixed a HTTP request forgery via character injection through HTTP/2 pseudo-headers.
