Unauthenticated data disclosure via page parameter overflow
Published Apr 23, 2024 · Updated Aug 7, 2024
Stack-based buffer overflow in Tenda FH1206 1.2.0.8(8155)_EN allows remote attackers to read sensitive data via a crafted page parameter. The addressNat handler processes the untrusted page value in stack storage without an adequate size boundary, although the public record does not identify the exact copy operation. No authentication or user interaction is required; the published assessment limits the demonstrated consequence to confidentiality loss.
