Descriptions

HAProxy before 2.8.2 accepts # as part of the URI component, which might allow remote attackers to obtain sensitive information or have unspecified other impact upon misinterpretation of a path_end rule, such as routing index.html#.png to a static server.

HAProxy anterior a 2.8.2 acepta # como parte del componente URI, lo que podría permitir a atacantes remotos obtener información confidencial o tener otro impacto no especificado tras una mala interpretación de una regla path_end, como enrutar index.html#.png a un servidor estático.
