Descriptions

Applications using the “Sensitive Headers” functionality in Spring Cloud Netflix Zuul 2.2.6.RELEASE and below may be vulnerable to bypassing the “Sensitive Headers” restriction when executing requests with specially constructed URLs. Applications that use Spring Security's StrictHttpFirewall (enabled by default for all URLs) are not affected by the vulnerability, as they reject requests that allow bypassing.

Unas aplicaciones que usan la funcionalidad de "Sensitive Headers" en Spring Cloud Netflix Zuul versiones 2.2.6.RELEASE y anteriores, pueden ser vulnerables al omitir la restricción "Sensitive Headers" cuando se ejecutan peticiones con URL especialmente construidas. Unas aplicaciones que usan StrictHttpFirewall de Spring Security (habilitado por defecto para todas las URL) no están afectadas por la vulnerabilidad, ya que rechazan unas peticiones que permiten la omisión
