Authenticated router crash via unchecked page formatting
Published Apr 17, 2024 · Updated Aug 2, 2024
Stack-based buffer overflow in Tenda W30E firmware 1.0.1.25(633) allows remote authenticated users to crash the router via a crafted request. The fromwebExcptypemanFilter handler appends the attacker-controlled page parameter to a stack buffer with sprintf without checking its capacity. Access to the web management interface and valid administrator credentials are required; the published proof of concept crashes the router, while reliable code execution is not established.
