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 (sub_42F32C function). The web interface reads the "lang" parameter and constructs Help URL strings using sprintf() into fixed-size stack buffers without proper length validation. Maliciously crafted input can overflow these buffers, potentially leading to 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 when the web interface processes the "lang" parameter. The parameter is used to build Help URL strings with sprintf() into fixed-size stack buffers without proper length checks. Malicious input can overflow these buffers, potentially causing arbitrary code execution or memory corruption without needing authentication.

Impact Analysis

The vulnerability can allow an attacker to execute arbitrary code or cause memory corruption on the affected router devices. This can lead to unauthorized control over the device, disruption of network services, or further compromise of the network connected to the router.
