Title
Pie Forms for WP <= 1.6 - Unauthenticated Arbitrary File Upload
Summary
The Pie Forms for WP plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.6 via the format_classic function. This is due to insufficient file type validation where the validate_classic method validates file extensions and sets error messages but does not prevent the file upload process from continuing. This makes it possible for unauthenticated attackers to upload files with dangerous extensions such as PHP, which makes remote code execution possible. In order to exploit this vulnerability, the attacker needs to guess the directory in which the file is placed (which is a somewhat predictable hash). In addition to that, the file name is generated using a secure hash method, limiting the exploitability of this vulnerability.

Esto se debe a una validaci\u00f3n insuficiente del tipo de archivo, donde el m\u00e9todo \u0027validate_classic\u0027 valida las extensiones de archivo y establece mensajes de error, pero no evita que el proceso de carga de archivos contin\u00fae. Esto permite a atacantes no autenticados cargar archivos con extensiones peligrosas como PHP, lo que hace posible la ejecuci\u00f3n remota de c\u00f3digo. Para explotar esta vulnerabilidad, el atacante necesita adivinar el directorio donde se coloca el archivo (que es un hash algo predecible). Adem\u00e1s de eso, el nombre del archivo se genera utilizando un m\u00e9todo de hash seguro, lo que limita la explotabilidad de esta vulnerabilidad."
