What is CVE-2020-28347?

The tdpServer on TP-Link Archer A7 AC1750 devices prior to version 201029 is susceptible to remote code execution. This vulnerability arises when attackers exploit the 'slave_mac' parameter, allowing them to execute arbitrary code on the device. The issue is a result of an incomplete fix for a previous vulnerability, CVE-2020-10882, which failed to properly handle shell quotes. This oversight exposes the device to unauthorized commands, posing a significant risk to network security.
