  # Exploit Title: JourneyMap Disk-space consumption exploit # Date: 23Nov2014 # Exploit Author: CovertCodes # Vendor Homepage: http://journeymap.techbrew.net/ # Software Link: http://journeymap.techbrew.net/download/ # Version: 5.0.0RC2 Ultimate Edition # Tested on: Linux     JourneyMap (http://journeymap.techbrew.net/) is a mapping mod for Minecraft.It comes included with some modpacks, and is enabled by default in the popular Feed the Beast client.JourneyMap opens a web server on the client which is configured to listen on port 8080.When the client is running, a remote, unauthenticated user can have JourneyMap save a screenshot of the game to the hard drive by accessing a specific URL, consuming hard drive space.Here's an example:   #!/bin/bash while true; do curl -o /dev/null 192.168.1.1:8080/action?type=savemap&mapType=day done   This works even when the client has paused the game (by pressing escape.)We include mapType=day because the software should refuse to save a screenshot if the client user is underground, and the game is set on hardcore mode.   Accessing the URL and triggering a screenshot will display a message on the client's screen, which may somewhat lessen the severity of this exploit.Further, it takes a long time to fill up disk using this technique.JourneyMap allows depth and resolution to be specified in the URL as well, though a few simple tests showed no change despite altering these parameters.If one were able to increase the depth and resolution of the image, the drive would fill up faster.   Tested with JourneyMap 5.0.0RC2 Ultimate Edition, but presumed to work on other versions as well.
