Improper limitation of a pathname to a restricted directory ('Path Traversal') issue exists in FitNesse releases prior to 20241026. If this vulnerability is exploited, an attacker may be able to know whether a file exists at a specific path, and/or obtain some part of the file contents under specific conditions.
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.
