CVE-2024-33215Public exploitNetwork attack vector

Unauthenticated memory corruption via mitInterface overflow

Published Apr 23, 2024 · Updated Aug 15, 2024

Stack-based buffer overflow in Tenda FH1206 1.2.0.8(8155)_EN allows remote attackers to corrupt memory via crafted mitInterface requests. The ip/goform/addressNat handler accepts an oversized mitInterface value and overwrites a stack buffer; public sources do not identify the copy routine or buffer size. No authentication or user interaction is required according to CISA's assessment, but the record does not specify whether exploitation ends in a crash or controlled code execution.
