CyberRota Analysis

AI-Generated

A vulnerability in RustFS allows an attacker to manipulate the target_user parameter in the AddServiceAccount function, leading to unauthorized ownership privileges for service accounts. This could enable attackers to gain elevated access and control over the storage system, posing significant risks to data integrity and confidentiality. Organizations using RustFS should prioritize applying the patch in version 1.0.0-beta.11 to mitigate potential exploitation.

Original NVD Description

RustFS is a distributed object storage system built in Rust. RustFS AddServiceAccount in rustfs/src/admin/handlers/service_account.rs accepts an attacker-controlled target_user after only checking CreateServiceAccountAdminAction, passes it to new_service_account, and prepare_service_account_auth sets is_owner for the resulting root-parent service account. This issue is fixed in version 1.0.0-beta.11.
