CVE-2024-4252Network attack vector

Authenticated memory corruption via groupIndex overflow

Published Apr 27, 2024 · Updated Aug 1, 2024

Stack-based buffer overflow in Tenda i22 1.0.0.3(4687) allows remote authenticated users to corrupt memory via groupIndex. Public records identify formSetUrlFilterRule and its groupIndex argument, but the referenced proof of concept is unavailable and the exact unsafe operation is undisclosed. A low-privileged web-management session is required, and public evidence does not establish whether exploitation causes a crash or permits code execution.
