This module exploits a command injection vulnerability in the tdpServer daemon (/usr/bin/tdpServer), running on the router TP-Link Archer A7/C7 (AC1750), hardware version 5, MIPS Architecture, firmware version 190726. The vulnerability can only be exploited by an attacker on the LAN side of the router, but the attacker does not need any authentication to abuse it. After exploitation, an attacker will be able to execute any command as root, including downloading and executing a binary from another host. This vulnerability was discovered and exploited at Pwn2Own Tokyo 2019 by the Flashback team (Pedro Ribeiro + Radek Domanski).
