Directory traversal vulnerability in view_private.php in Keep It Simple Guest Book (KISGB) 5.0.0 and earlier allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the tmp_theme parameter. NOTE: 5.1.1 is also reportedly affected.
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.
