Memory corruption via unchecked GO and page values
Published Apr 25, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Tenda 4G300 1.01.42 allows remote authenticated users to corrupt memory via crafted GO or page values. The sub_41E858 function places those attacker-controlled values into a fixed-size stack buffer without enforcing its capacity. Access to the management interface is required; successful corruption can crash the service or redirect its execution.
