Tenda AX1803 Stack-Based Buffer Overflow Vulnerability in WiFi MAC Filter Configuration

A critical stack-based buffer overflow vulnerability has been identified in the Tenda AX1803 router, specifically in version 1.0.0.1. The issue arises in the 'formSetWifiMacFilterCfg' function within the '/goform/setWifiFilterCfg' file. The vulnerability can be exploited remotely by manipulating the 'deviceList' parameter, leading to potential unauthorized access or control.

Impact

Exploitation of this vulnerability causes a stack-based buffer overflow, which can commonly lead to arbitrary code execution or causing the device to crash.

Reproduction

The vulnerability can be reproduced by sending a crafted request to the '/goform/setWifiFilterCfg' endpoint, including a 'deviceList' parameter that exceeds the buffer size, thereby causing a stack-based overflow.
