CVE-2022-31028

Possible DDOS by establishing keep-alive connections with anonymous HTTP clients in MinIO

Published Jun 3, 2022 CVSS 3.1 · 7.5 High EPSS 3.0% KEV · Not listed
Description
MinIO is a multi-cloud object storage solution. Starting with version RELEASE.2019-09-25T18-25-51Z and ending with version RELEASE.2022-06-02T02-11-04Z, MinIO is vulnerable to an unending go-routine buildup while keeping connections established due to HTTP clients not closing the connections. Public-facing MinIO deployments are most affected. Users should upgrade to RELEASE.2022-06-02T02-11-04Z to receive a patch. One possible workaround is to use a reverse proxy to limit the number of connections being attempted in front of MinIO, and actively rejecting connections from such malicious clients.
