Summary

RustFS has IAM Incorrect Authorization in ImportIam that Allows Privilege Escalation

Details

RustFS is a distributed object storage system built in Rust. Prior to version 1.0.0-alpha.79, he ImportIam admin API validates permissions using ExportIAMAction instead of ImportIAMAction, allowing a principal with export-only IAM permissions to perform import operations. Since importing IAM data performs privileged write actions (creating/updating users, groups, policies, and service accounts), this can lead to unauthorized IAM modification and privilege escalation. Version 1.0.0-alpha.79 fixes the issue.
