In the web interface of Parallels Remote Application Server (RAS) 15.5 Build 16140, a vulnerability exists due to improper validation of the file path when requesting a resource under the "RASHTML5Gateway" directory. A remote, unauthenticated attacker could exploit this weakness to read arbitrary files from the vulnerable system using path traversal sequences.
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.
