Submit #757240: Tenda AC8V4 V16.03.34.06 Stack-based Buffer Overflowinfo

TitleTenda AC8V4 V16.03.34.06 Stack-based Buffer Overflow
DescriptionAn issue was discovered in Tenda AC8V4 V16.03.34.06. The webCgiGetUploadFile function in the httpd service fails to validate the length of the boundary parameter from the Content-Type header, allowing remote attackers to overflow a fixed-size stack buffer of 64 bytes and achieve arbitrary code execution or denial of service via a crafted POST request to /cgi-bin/UploadCfg.
