Description

Impact

An authorized user can upload a zip-format plugin with a crafted plugin.yaml, or a crafted aclpolicy yaml file, or upload an untrusted project archive with a crafted aclpolicy yaml file, that can cause the server to run untrusted code on Rundeck Community or Enterprise Edition. An authenticated user can make a POST request, that can cause the server to run untrusted code on Rundeck Enterprise Edition.

The zip-format plugin issues requires authentication and authorization to these access levels, and affects all Rundeck editions:

  • admin level access to the system resource type

The ACL Policy yaml file upload issues requires authentication and authorization to these access levels, and affects all Rundeck editions:

  • create update or admin level access to a project_acl resource
  • create update or admin level access to the system_acl resource

The unauthorized POST request requires authentication, but no specific authorization, and affects Rundeck Enterprise only.
