Submit #769173: 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 formSetAutoPing at the /goform/setAutoPing endpoint. The handler copies the ping1 POST parameter into a fixed-size stack buffer without validating length. A crafted request with an excessively long ping1 value causes stack corruption, leading to a crash and possible code execution. The vulnerable flow is reached when linkEn=1 and ping1 is processed.
