AI-suggested

Organizations should immediately upgrade vitodeploy vito to version 3.20.3 or later, where the authorization checks have been properly implemented. Until the upgrade is applied, restrict workflow write access strictly to trusted users and audit existing permissions to minimize exposure. Implement network segmentation and access controls to limit the ability of compromised accounts to affect multiple projects. Conduct thorough reviews of server_id parameters and workflow actions in custom integrations or automation scripts to detect unauthorized cross-project references. Monitor logs for unusual site-creation activities involving foreign server IDs. Additionally, enforce the principle of least privilege for all users and consider multi-factor authentication to reduce the risk of credential compromise. Regularly review and update security policies around deployment workflows to ensure robust authorization enforcement.

Description

Vito is a self-hosted web application that helps manage servers and deploy PHP applications into production servers. Prior to version 3.20.3, a missing authorization check in workflow site-creation actions allows an authenticated attacker with workflow write access in one project to create/manage sites on servers belonging to other projects by supplying a foreign server_id. This issue has been patched in version 3.20.3.
