Executive Summary

This vulnerability is a stack-based buffer overflow in the mtk_dut binary of Linksys E7350 routers (Firmware 1.1.00.032). It occurs because the function sub_4045A8 reads up to 256 bytes from a system file into a local buffer and then copies it into a smaller caller-provided buffer without checking boundaries. If an attacker controls the contents of that system file, they can cause a buffer overflow, leading to memory corruption, denial of service, or potentially arbitrary code execution.

Impact Analysis

This vulnerability can lead to memory corruption, denial of service, or potentially allow an attacker to execute arbitrary code on the affected device. This means an attacker with local access could disrupt the router's operation or take control of it.
