CVE-2024-24747Public exploitNetwork attack vector

Privilege escalation via unchecked service-account policy edits

Published Jan 31, 2024 · Updated Aug 1, 2024

Improper privilege management in MinIO before RELEASE.2024-01-31T20-20-33Z allows remote authenticated users to expand S3 access. The UpdateServiceAccount handler let an access key edit its own session policy without requiring admin:UpdateServiceAccount, overriding inherited S3 restrictions. A service-account access key with inherited admin actions can replace its limited policy and read or write data across the deployment.
