Descriptions

Incorrect caching of responses to requests including an Authorization header in HAProxy 1.8.0 through 1.8.9 (if cache enabled) allows attackers to achieve information disclosure via an unauthenticated remote request, related to the proto_http.c check_request_for_cacheability function.

El cacheado incorrecto de respuestas a peticiones que incluyen una cabecera Authorization en HAProxy, de la versión 1.8.0 hasta la 1.8.9 (si cache está habilitado) permite que los atacantes logren la divulgación de información mediante una petición remota no autenticada. Esto está relacionado con la función check_request_for_cacheability en proto_http.c.

HAProxy is a TCP/HTTP reverse proxy which is particularly suited for high availability environments. Issues addressed include denial of service and information leakage vulnerabilities.
