Memory corruption via unchecked list1 handling
Published Apr 25, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Tenda 4G300 firmware 1.01.42 allows remote authenticated users to corrupt memory via list1. The sub_429A30 function processes the attacker-controlled list1 argument without enforcing the destination stack buffer's bounds. Low-privileged access to the network service is required, and overflowing the stack can crash the service or alter its control flow.
