      "value": "vBulletin through 5.3.x on Windows allows remote PHP code execution because a require_once call is reachable with an unauthenticated request that can include directory traversal sequences to specify an arbitrary pathname, and because ../ traversal is blocked but ..\\ traversal is not blocked. For example, an attacker can make an invalid HTTP request containing PHP code, and then make an index.php?routestring= request with enough instances of \"..\" to reach an Apache HTTP Server log file."

Por ejemplo, un atacante puede realizar una petici\u00f3n HTTP inv\u00e1lida que contiene c\u00f3digo PHP y, a continuaci\u00f3n, realizar una petici\u00f3n index.php?routestring= con las suficientes instancias de \"..\" para alcanzar un archivo de registro de Apache HTTP Server."
