Improper Authorization in Apache CloudStack Project Roles

Publication date: 2026-08-21

Last updated on: 2026-08-21

Assigner: Apache Software Foundation

Description
Improper authorization for CRUD operations on Project Roles and Project Role permissions for domain admins in CloudStack. A Domain Admin can create, update, delete, and list project roles and project role permissions for projects in any domain, not just their own. The check only confirms the caller is a Domain Admin, without verifying whether the target project belongs to their domain or subdomain. This allows a malicious Domain Admin to tamper with project roles and permissions across unrelated domains. This issue affects Apache CloudStack: from 4.15.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.

Executive Summary

This vulnerability involves improper authorization in Apache CloudStack where a Domain Admin can perform CRUD operations on project roles and permissions for projects outside their domain. The system only checks if the user is a Domain Admin but fails to verify if the target project belongs to their domain or subdomain.

Detection Guidance

This vulnerability involves improper authorization checks for CRUD operations on project roles and permissions by Domain Admins. To detect it, review CloudStack logs for unauthorized modifications to project roles or permissions across domains. Check for Domain Admin accounts performing actions outside their assigned domain. No specific commands are provided in the context.

Impact Analysis

A malicious Domain Admin could tamper with project roles and permissions across unrelated domains, potentially leading to unauthorized access, data breaches, or disruption of services in projects they should not control.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements for data protection and access control in standards like GDPR and HIPAA. It undermines the principle of least privilege and data segregation.

Mitigation Strategies

Upgrade Apache CloudStack to version 4.20.3.1 or 4.22.1.1 or later to fix the authorization issue.
