WADashboard API in Advantech WebAccess 8.3.1 and 8.3.2 allows remote authenticated attackers to read any file on the filesystem due to a directory traversal vulnerability in the readFile API.
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.
