A vulnerability, which was classified as problematic, was found in ChestnutCMS up to 1.5.3. Affected is the function readFile of the file /dev-api/cms/file/read. The manipulation of the argument filePath leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.
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.
