CVE-2024-30589Public exploitNetwork attack vector

Unauthenticated stack corruption via entrys parameter

Published Mar 28, 2024 · Updated Aug 13, 2024

Stack-based buffer overflow in Tenda FH1202 firmware 1.2.0.14(408) allows remote attackers to corrupt memory via the entrys parameter. The fromAddressNat function accepts entrys, but public records do not identify the unsafe copy operation or destination stack buffer. Network access is sufficient and requires neither authentication nor user interaction; successful exploitation corrupts the process stack.
