CVE-2021-2317Network attack vector

Unauthenticated takeover via undisclosed management-console flaw

Published Apr 22, 2021 · Updated Sep 26, 2024

A Management Console flaw in Oracle Cloud Infrastructure Storage Gateway before 1.4 allows remote attackers to take over the gateway via HTTP. Oracle identifies the affected locus only as the Management Console and has not published the request, endpoint, or incorrect operation that enables compromise. Unauthenticated network access to the console is sufficient; successful exploitation grants control of the gateway and can significantly affect connected products.
