Descriptions

CRLF injection vulnerability in the Undertow web server in WildFly 10.0.0, as used in Red Hat JBoss Enterprise Application Platform (EAP) 7.x before 7.0.2, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.

Vulnerabilidad de inyección CRLF en el servidor web Undertow en WildFly 10.0.0, tal como se utiliza en Red Hat JBoss Enterprise Application Platform (EAP) 7.x en versiones anteriores a 7.0.2, permite a atacantes remotos inyectar cabeceras HTTP arbitrarias y llevar a cabo ataques de separación de respuesta HTTP a través de vectores no especificados.

It was reported that EAP 7 Application Server/Undertow web server is vulnerable to the injection of arbitrary HTTP headers, and also response splitting, due to insufficient sanitization and validation of user input before the input is used as part of an HTTP header value.
