An Information Disclosure / Data Modification issue exists in article2pdf_getfile.php in the article2pdf Wordpress plugin 0.24, 0.25, 0.26, 0.27. A URL can be constructed which allows overriding the PDF file's path leading to any PDF whose path is known and which is readable to the web server can be downloaded. The file will be deleted after download if the web server has permission to do so. For PHP versions before 5.3, any file can be read by null terminating the string left of the file extension.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
