A stack-based buffer overflow vulnerability has been identified in the Tenda AC8 router, specifically in version 16.03.34.06. The issue arises in the webCgiGetUploadFile function within the Httpd service, where the boundary parameter of the Content-Type header is not properly validated. This flaw allows remote attackers to overflow a fixed-size stack buffer of 64 bytes, potentially leading to arbitrary code execution or a denial-of-service condition. The vulnerability can be exploited by sending a crafted POST request to the /cgi-bin/UploadCfg endpoint.
