Summary

The TP-Link Archer C5 devices, specifically version V2_160201_US, are susceptible to remote command execution due to improper handling of input in the 'wan_dyn_hostname' line of an encrypted configuration file. This vulnerability allows an attacker to execute arbitrary commands on the device if they can access the web GUI, particularly by using shell metacharacters. In certain scenarios, the default admin password may provide an additional attack vector for unauthorized users.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
