An attacker can make an authenticated HTTP request to trigger these vulnerabilities.This vulnerability exists in the `cli_mac` POST parameter.
A stack-based buffer overflow vulnerability has been identified in the Wavlink AC3000 router, specifically in the internet.cgi file's set_qos() function. This vulnerability affects version M33A8.V5030.210505. The issue arises from the improper handling of POST parameters, particularly 'cli_mac', 'cli_name', and 'en_enable', which are all processed without length validation. An authenticated attacker can exploit this vulnerability by sending a crafted HTTP request that overwrites the stack with malicious data, potentially leading to arbitrary code execution.
