Executive Summary

This vulnerability is a stack-based buffer overflow found in the TOTOLINK A3002RU_V3 router firmware version 3.0.0-B20220304.1804. It occurs via the static_ipv6 parameter in the formIpv6Setup function. A buffer overflow happens when more data is written to a buffer than it can hold, potentially allowing an attacker to overwrite adjacent memory.

Impact Analysis

A stack-based buffer overflow can allow an attacker to execute arbitrary code, cause a denial of service (crash the device), or gain unauthorized access to the device. This could lead to compromise of the router, interception or manipulation of network traffic, and potentially further attacks on connected devices.
