Directory traversal vulnerability in includes/lib/gz.php in Chyrp 2.0 and earlier allows remote attackers to read arbitrary files via a .. (dot dot) in the file parameter, a different vulnerability than CVE-2011-2744.
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.
