Descriptions

An issue was discovered in the AccessKeys AccessPress Anonymous Post Pro plugin through 3.1.9 for WordPress. Improper input sanitization allows the attacker to override the settings for allowed file extensions and upload file size, related to inc/cores/file-uploader.php and file-uploader/file-uploader-class.php. This allows the attacker to upload anything they want to the server, as demonstrated by an action=ap_file_upload_action&allowedExtensions[]=php request to /wp-admin/admin-ajax.php that results in a .php file upload and resultant PHP code execution.

Se ha descubierto una vulnerabilidad en el plugin AccessKeys AccessPress Anonymous Post Pro hasta la versión 3.1.9 para WordPress. Un saneamiento de entradas incorrecto permite que el atacante invalide la configuración para las extensiones de archivo permitidas y la subida de archivos. Esto está relacionado con inc/cores/file-uploader.php y file-uploader/file-uploader-class.php. Esto permite que el atacante suba lo que quiera al servidor, tal y como se demuestra con una petición action=ap_file_upload_actionallowedExtensions[]=php a /wp-admin/admin-ajax.php que resulta en la subida de un archivo .php y en la ejecución de código PHP como resultado.

Accesspress Anonymous Post Pro versions prior to 3.2.0 suffers from an arbitrary file upload vulnerability.
