Descriptions

The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more.

El analizador de URLs de Curl acepta erróneamente separadores de URL codificados en porcentaje, como "/", cuando decodifica la parte del nombre del host de una URL, convirtiéndola en una URL *diferente* que usa un nombre de host incorrecto cuando es recuperado posteriormente. Por ejemplo, una URL como "http://example.com%2F127.0.0.1/", sería permitida por el analizador y sería transpuesta a "http://example.com/127.0.0.1/". Este fallo puede usarse para omitir filtros, comprobaciones y otras cosas
