Descriptions

WordPress through 5.0.3 allows Path Traversal in wp_crop_image(). An attacker (who has privileges to crop an image) can write the output image to an arbitrary directory via a filename containing two image extensions and ../ sequences, such as a filename ending with the .jpg?/../../file.jpg substring.

WordPress hasta la versión 5.0.3 permite saltos de directorio en wp_crop_image(). Un atacante (con privilegios para recortar una imagen) puede escribir la imagen de salida a un directorio arbitrario mediante un nombre de archivo que contiene dos extensiones de imagen y de ../, como por ejemplo un nombre de archivo que termina con la subcadena .jpg?/../../file.jpg.
