Unrestricted file upload vulnerability in lib_nonajax.php in the CformsII plugin 14.7 and earlier for WordPress allows remote attackers to execute arbitrary code by uploading a file with an executable extension via the cf_uploadfile2[] parameter, then accessing the file via a direct request to the file in the default upload directory.
