Speco Web Viewer through 2021-05-12 allows Directory Traversal via GET request for a URI with /.. at the beginning, as demonstrated by reading the /etc/passwd file.
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.
