Executive Summary

This vulnerability exists in the UTT 进取 520W version 1.7.7-180627 device, specifically in the strcpy function within the /goform/formPolicyRouteConf file. The issue arises when the argument GroupName is manipulated, causing a buffer overflow. This means that an attacker can send specially crafted input to overflow the buffer, potentially leading to unexpected behavior or control over the device.

The attack can be executed remotely, meaning an attacker does not need physical access to the device to exploit this vulnerability.

Impact Analysis

Exploiting this buffer overflow vulnerability can lead to severe impacts including unauthorized control over the affected device. Since the vulnerability allows remote exploitation, an attacker could potentially execute arbitrary code, disrupt device functionality, or gain elevated privileges.

The CVSS scores indicate a high severity level, with impacts on confidentiality, integrity, and availability, meaning sensitive information could be exposed or altered, and the device could be rendered unavailable.
