Summary: YAML deserialization can run untrusted code

Details: ### 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. ### Patches Versions 3.4.3, 3.3.14 ### Workarounds Please visit [https://rundeck.com/security](https://rundeck.com/security) for information about specific workarounds. ### For more information If you have any questions or comments about this advisory: * Email us at [[email protected]](mailto:[email protected]) To report security issues to Rundeck please use the form at [https://rundeck.com/security](https://rundeck.com/security) Reporter: Rojan Rijal from Tinder Red Team
