CVE-2024-32307Public exploitNetwork attack vector

Memory corruption via unchecked PPW parameter length

Published Apr 17, 2024 · Updated Aug 9, 2024

Stack-based buffer overflow in Tenda FH1205 firmware 2.0.0.7(775) allows remote attackers to corrupt memory via a crafted PPW value. The fromWizardHandle function accepts an overlong PPW parameter into a stack buffer without a documented bounds check; the exact copy primitive is undisclosed. An unauthenticated remote attacker must satisfy unspecified high-complexity conditions; the published assessment limits impact to confidentiality and integrity.
