Dell EMC AppSync versions from 3.9 to 4.3 contain a path traversal vulnerability in AppSync server. A remote unauthenticated attacker may potentially exploit this vulnerability to gain unauthorized read access to the files stored on the server filesystem, with the privileges of the running web application.
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.
