Stack-Based Buffer Overflow in thttpd for GeoVision GV-LPC2011 and GV-LPC2211

Executive Summary

This vulnerability is an unauthenticated stack-based buffer overflow found in the thttpd component of GeoVision GV-LPC2011 and GV-LPC2211 devices running version 1.12 or earlier.

It occurs because the software does not properly check the length of web request parameters in a specific request path, allowing an attacker to send an overly long HTTP request.

Exploiting this flaw can cause memory corruption, which may lead to denial of service or even allow the attacker to execute arbitrary code remotely.
