MinIO Information Disclosure Vulnerability
MinIO contains a vulnerability in a cluster deployment where MinIO returns all environment variables, which allows for information disclosure.
A remote attacker, without authentication, can achieve full data confidentiality loss. Federal agencies are required to remediate by 2023-05-12 under CISA BOD 22-01.
This is a Information Disclosure (CWE-200) vulnerability in MinIO MinIO. Minio is a Multi-Cloud Object Storage framework. In a cluster deployment starting with RELEASE.2019-12-17T23-16-33Z and prior to RELEASE.2023-03-20T20-16-18Z, MinIO returns all environment variables, including `MINIO_SECRET_KEY` and `MINIO_ROOT_PASSWORD`, resulting in information disclosure. All users of distributed deployment are impacted. All users are advised to upgrade to RELEASE.2023-03-20T20-16-18Z. Exploitation requires remote network access, low attack complexity, no authentication required, and no user interaction required.
