Directory traversal vulnerability in the Avatar Uploader module 6.x-1.x before 6.x-1.2 and 7.x-1.x before 7.x-1.0-beta6 for Drupal allows remote authenticated users to read arbitrary files via a .. (dot dot) in the path of a cropped picture in the uploader panel.
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.
