CVE-2022-30049Public exploitNetwork attack vector

Unauthenticated intranet scanning via unrestricted URL fetch

Published May 15, 2022 · Updated Aug 3, 2024

SSRF in Ruifang-tech Rebuild 2.8.3 allows remote attackers to expose the server's real IP address and probe intranet resources via fileurl. The fetchRemoteJson path accepts a caller-supplied URL and passes it to an HTTP URL GET operation without restricting the destination. No authentication or user interaction is required, and the bounded consequence is network-origin disclosure and intranet scanning.
