Description

An issue was discovered in zola 0.13.0 through 0.17.2. The custom implementation of a web server, available via the "zola serve" command, allows directory traversal. The handle_request function, used by the server to process HTTP requests, does not account for sequences of special path control characters (../) in the URL when serving a file, which allows one to escape the webroot of the server and read arbitrary files from the filesystem.

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.
