CVE-2024-2984Public exploitNetwork attack vector

Authenticated memory corruption via unchecked funcpara1 length

Published Mar 27, 2024 · Updated Aug 1, 2024

Stack-based buffer overflow in Tenda FH1202 1.2.0.14(408) allows remote authenticated users to corrupt memory via funcpara1. The formSetCfm handler for /goform/setcfm processes an oversized funcpara1 value without a sufficient bounds check, overwriting its stack buffer. Low-privileged access to the router interface is required; exploitation can crash the service or compromise control flow.
