description: An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8. There is Arbitrary File Upload. The BaseController class, that each of the service controllers derives from, allows for the upload of arbitrary files. If the HTTP request is a multipart/form-data POST request, any parameters with a filename entry will have their content written to a file in the Vocera upload-staging directory with the specified filename in the parameter.
