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 CX12L device, specifically in the function fromP2pListFilter located in the file /goform/P2pListFilter. It is caused by improper handling of the argument 'page', which leads to a stack-based buffer overflow. This means that an attacker can manipulate the input to overflow the buffer on the stack, potentially causing unexpected behavior or allowing code execution.

The attack must originate from within the local network, meaning remote attackers from outside the network cannot exploit this vulnerability directly.

The exploit for this vulnerability has been made public, increasing the risk of it being used maliciously.

Impact Analysis

Exploitation of this vulnerability can lead to a stack-based buffer overflow, which may allow an attacker on the local network to execute arbitrary code or cause the device to crash.

This can result in denial of service or unauthorized control over the affected device, potentially compromising the security and stability of your local network.
