Descriptions

The sapi_header_op function in main/SAPI.c in PHP before 5.3.11 and 5.4.x before 5.4.0RC2 does not check for %0D sequences (aka carriage return characters), which allows remote attackers to bypass an HTTP response-splitting protection mechanism via a crafted URL, related to improper interaction between the PHP header function and certain browsers, as demonstrated by Internet Explorer and Google Chrome.

La función sapi_header_op en el archivo main/SAPI.c en PHP anterior a versión 5.3.11 y versiones 5.4.x anteriores a 5.4.0RC2, no comprueba si hay secuencias de %0D (también se conoce como caracteres de retorno de acarreo), lo que permite a atacantes remotos omitir un mecanismo de protección de división de respuesta HTTP por medio de una URL diseñada, relacionada con la interacción inapropiada entre la función de PHP header y ciertos navegadores, como es demostrado por Internet Explorer y Google Chrome.
