CWE ID Description
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
CWE-121 A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

Executive Summary

This vulnerability exists in the Tenda F451 device running version 1.0.0.7. It affects the function formWrlsafeset in the file /goform/AdvSetWrlsafeset. By manipulating the argument mit_ssid, an attacker can cause a stack-based buffer overflow. This type of vulnerability allows an attacker to overwrite parts of the memory stack, potentially leading to arbitrary code execution.

The attack can be performed remotely, meaning an attacker does not need physical access to the device to exploit it. Additionally, the exploit code is publicly available, increasing the risk of exploitation.

Impact Analysis

Exploitation of this vulnerability can lead to severe impacts including unauthorized remote code execution on the affected device. This can allow attackers to take control of the device, disrupt its normal operation, or use it as a foothold to attack other systems on the network.

Given the high severity scores (CVSS v3.1 score of 8.8 and v2.0 score of 9.0), the vulnerability poses a significant security risk, potentially compromising confidentiality, integrity, and availability of the device and connected systems.
