www/getfile.php in WPO WebPageTest 19.04 on Windows allows Directory Traversal (for reading arbitrary files) because of an unanchored regular expression, as demonstrated by the a.jpg\.. substring.
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.
