Absolute path traversal vulnerability in nukestyles.com viewpage.php addon for PHP-Nuke allows remote attackers to read arbitrary files via a full pathname in the file parameter. NOTE: This was originally reported as an issue in PHP-Nuke 6.5, but this is an independent addon.
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.
