chiyu-tech bf-450m firmware

Published Atomicorp research notes for CVEs affecting chiyu-tech bf-450m firmware where WAF protections were observed during testing or engineering review.

These notes are not intended to represent the full set of vulnerabilities mitigated by Atomicorp products and should not be interpreted as a coverage matrix, certification list, or census of protected CVEs.

Atomicorp WAF protections are primarily designed around attack techniques and exploit behaviors rather than individual vulnerability identifiers. A published research note documents a positive research finding related to that CVE. If a CVE is absent from these notes, no conclusion should be drawn about protection status.
