Submit #769177: Tenda W3 V1.0.0.3(2204) Buffer Overflowinfo

TitleTenda W3 V1.0.0.3(2204) Buffer Overflow
DescriptionA stack-based buffer overflow exists in Tenda w3 V1.0.0.3(2204) in the HTTP handler formexeCommand exposed at /goform/exeCommand. The POST parameter cmdinput is copied into a fixed-length stack buffer without length validation. An overly long cmdinput value overwrites the stack, resulting in a crash and potential code execution within the httpd process.
