CVE-2022-45429Network attack vector

Unauthenticated internal resource access via crafted URLs

Published Dec 27, 2022 · Updated Apr 11, 2025

SSRF in Dahua DSS products allows remote attackers to access internal resources by submitting URLs that follow special concatenation rules. The server accepts attacker-controlled concatenated links that satisfy undisclosed rules and fetches the resulting URL from its trusted network context. No authentication or user interaction is required; reachable deployments expose internal resources, but Dahua has not identified the affected endpoint or bounded the available data and actions.
