CVE-2024-2989Public exploitNetwork attack vector

Authenticated memory corruption via oversized page parameter

Published Mar 27, 2024 · Updated Aug 22, 2024

Stack-based buffer overflow in Tenda FH1203 2.0.1.6 allows remote authenticated users to corrupt memory through a crafted page parameter. The fromNatStaticSetting handler at /goform/NatStaticSetting accepts an oversized page value into stack storage without enforcing its destination bound. Low-privileged management access is required; the public record establishes memory corruption but no specific code-execution or device-crash result.
