Directory traversal vulnerability in CommunicationServlet in HP Service Virtualization 3.x before 3.50.1, when the AutoPass license server is enabled, allows remote attackers to create arbitrary files and consequently execute arbitrary code via unspecified vectors, aka ZDI-CAN-2031.
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.
