KEV

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-120	The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.

Attack-Flow Graph

Executive Summary

This vulnerability exists in the Edimax BR-6208AC device up to version 1.02. It involves a buffer overflow caused by manipulation of the argument pptpDfGateway in an unknown function within the file /goform/setWAN. The vulnerability can be exploited remotely.

A buffer overflow occurs when more data is written to a buffer than it can hold, potentially allowing an attacker to execute arbitrary code or cause a denial of service.

The exploit for this vulnerability is publicly available, and the vendor did not respond to early disclosure attempts.

Impact Analysis

Exploitation of this vulnerability can lead to severe impacts including remote code execution, denial of service, or unauthorized control over the affected device.

Because the attack can be initiated remotely and the vulnerability involves a buffer overflow, an attacker could potentially take control of the device or disrupt its normal operation.
