Description Andrej Nemec 2017-02-02 17:00:47 UTC 
Since version 0.9.8, Guacamole has provided access to files via a file browser located in the Guacamole menu. If file transfer is enabled on a remote desktop connection, this file browser displays a navigable hierarchy of files to which the user has access.

A cross-site scripting (XSS) vulnerability was discovered and reported by Niv Levy through which files with specially-crafted names could lead to JavaScript execution if file transfer is enabled to a location which is shared by multiple users.
