Description

Camaleon CMS before 2.9.3 contains a path traversal vulnerability that allows users with only the media permission to write arbitrary files by supplying ../ sequences in the name parameter. Attackers can send a base64 data: URI to the crop_url media action to write an ERB template into a theme's views directory, which executes when rendered.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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.
