Attack-Flow Graph

Executive Summary

This vulnerability is a stack-based buffer overflow in the Tenda AX3 firmware version 16.03.12.11, specifically in the formGetIptv function. It occurs because the stbpvid stack buffer is not handled properly, which can lead to memory corruption and potentially allow an attacker to execute code remotely.

Impact Analysis

The vulnerability can lead to severe impacts including remote code execution, which means an attacker could take control of the affected device without authorization. This can result in compromised device integrity, data loss, or further attacks on connected networks.
