Description
A stack buffer overflow vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) Router firmware within the cstecgi.cgi binary (setDefResponse function). The binary reads the "IpAddress" parameter from a web request and copies it into a fixed-size stack buffer using strcpy() without any length validation. Maliciously crafted input can overflow the buffer, leading to potential arbitrary code execution or memory corruption, without requiring authentication.

Executive Summary

This vulnerability is a stack buffer overflow in the ToToLink LR1200GB and NR1800X router firmware. It occurs in the cstecgi.cgi binary's setDefResponse function, where the "IpAddress" parameter from a web request is copied into a fixed-size stack buffer using strcpy() without checking the input length. This allows an attacker to send specially crafted input that overflows the buffer, potentially causing arbitrary code execution or memory corruption without needing to authenticate.

Impact Analysis

The vulnerability can allow an attacker to execute arbitrary code or corrupt memory on the affected router remotely without authentication. This could lead to full compromise of the device, allowing the attacker to control the router, intercept or manipulate network traffic, disrupt network services, or use the device as a foothold for further attacks.
