Attack-Flow Graph

Executive Summary

This vulnerability is a logic flaw in the TP-Link Archer C20 v6.0 and Archer AX53 v1.0 devices, specifically in the TDDP module. It allows attackers who are on an adjacent network to execute administrative commands such as factory reset and device reboot without needing any credentials. This means unauthorized users nearby can remotely trigger these commands, potentially disrupting the device's normal operation.

Impact Analysis

The vulnerability can impact you by allowing attackers on an adjacent network to remotely cause your device to reboot or perform a factory reset without authorization. This can lead to loss of your device's configuration settings and interruption of device availability, potentially causing network downtime or loss of connectivity.

Mitigation Strategies

To mitigate this vulnerability, update the firmware of your TP-Link Archer C20 v6.0 and Archer AX53 v1.0 devices to the latest versions provided by TP-Link. Check the official TP-Link download pages for Archer AX53 and Archer C20 to obtain the latest firmware that addresses this issue. [1, 2]
