Directory traversal vulnerability in the PicSell (com_picsell) component 1.0 for Joomla! allows remote attackers to read arbitrary files via a .. (dot dot) in the dflink parameter in a prevsell dwnfree action to index.php.
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.
