Authenticated memory corruption via oversized funcpara1 value
Published Mar 27, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Tenda FH1203 2.0.1.6 allows remote authenticated users to corrupt memory via a crafted funcpara1 value. The formSetCfm function at /goform/setcfm accepts the oversized value without enforcing the destination stack buffer's bounds; the exact copy operation is undisclosed. Low-privileged management access is required, and exploitation can crash the service or alter execution flow within the router process.
