CVE-2024-25373

Authenticated memory corruption via unchecked page copy

Published Feb 15, 2024 · Updated Nov 12, 2024

Stack-based buffer overflow in Tenda AC10 V4.0 firmware 16.03.10.20 allows remote authenticated users to corrupt memory via crafted page input. The sub_49B384 function copies the page value into a stack buffer without checking whether it fits, overwriting adjacent memory. Access requires an authenticated account and adjacent-network reachability; the public record does not establish code execution, a crash, or another concrete consequence.
