The web application of some Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) was vulnerable to path traversal, allowing an unauthenticated user to retrieve arbitrary files, or check if files or folders existed within the file system.
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.
