Vulnerability Details CVE-2018-15490
An issue was discovered in ExpressVPN on Windows. The Xvpnd.exe process (which runs as a service with SYSTEM privileges) listens on TCP port 2015, which is used as an RPC interface for communication with the client side of the ExpressVPN application. A JSON-RPC protocol over HTTP is used for communication. The JSON-RPC XVPN.GetPreference and XVPN.SetPreference methods are vulnerable to path traversal, and allow reading and writing files on the file system on behalf of the service.
