Vulnerable Application

The following Geutebruck products using firmware versions <= 1.12.0.27, firmware version 1.12.13.2 or firmware version 1.12.14.5:

  • Encoder and E2 Series Camera models:

    • G-Code:

      • EEC-2xxx

    • G-Cam:

      • EBC-21xx

      • EFD-22xx

      • ETHC-22xx

      • EWPC-22xx

Many brands use the same firmware:

  • UDP Technology (which is also the supplier of the firmware for the other vendors)

  • Ganz

  • Visualint

  • Cap

  • THRIVE Intelligence

  • Sophus

  • VCA

  • TripCorps

  • Sprinx Technologies

  • Smartec

  • Riva

This module has been tested on a Geutebruck 5.02024 G-Cam EFD-2250 running the latest firmware version 1.12.0.27.

Description

This module will take an existing session on a vulnerable Geutebruck Camera and will allow the user to either freeze the camera and display the last image from the video stream, display an image on the camera, or restore the camera back to displaying the current feed/stream.

Users can find additional details of the related vulnerabilities on the blogpost page at https://www.randorisec.fr/udp-technology-ip-camera-vulnerabilities/.

Verification Steps

Freezing camera stream on the current image

  1. Launch msfconsole

  2. Get a shell using one of the published Getebruck exploits

  3. Do: use post/linux/manage/geutebruck_post_exp

  4. Do: set SESSION <session number of the Geutebruck shell>

  5. Do: set action FREEZE_CAMERA

  6. Do: run

  7. The image should be frozen

Replacing camera stream with a custom image

  1. Launch msfconsole

  2. Get a shell using one of the published Getebruck exploits

  3. Do: use post/linux/manage/geutebruck_post_exp

  4. Do: set SESSION <session number of the Geutebruck shell>

  5. Do: set action REPLACE_IMAGE

  6. Do: set IMAGE /local/image/path/to/upload

  7. Do: run

  8. The image should be replaced by the custom one

Restoring the current camera stream

  1. Launch msfconsole

  2. Get a shell using one of the published Getebruck exploits

  3. Do: use post/linux/manage/geutebruck_post_exp

  4. Do: set SESSION <session number of the Geutebruck shell>

  5. Do: set action RESUME_STREAM

  6. Do: run

  7. The stream should be resumed
