Short explanation
In Argo CD, when --enable-helm is enabled for kustomize build, helmGlobals.configHome can point Helm directories to a repository-controlled location, allowing command execution inside argocd-repo-server.
This vulnerability allows attackers to execute commands as the repo-server user and compromise repository credentials and other process-accessible data.
What should be done?
- Follow the vendor advisory for update recommendations.
- Review the --enable-helm configuration status.
Chain of evidence and sources
Argo CD, kustomize build için --enable-helm etkinleştirildiğinde argocd-repo-server içinde komut çalıştırılmasına izin veren bir güvenlik açığı barındırmaktadır.
Saldırganlar bu açığı istismar etmek için Kustomization ve eklentiyi bir Git deposuna commit edebilir veya dosya yükleme yolunu kullanabilir.
Show the technical text from the sources
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From 2.1.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, when an operator has enabled --enable-helm for kustomize build, helmGlobals.configHome can point Helm's config and data directories at a repository-controlled location. Helm automatically loads a downloader plugin from `<configHome>/.data/plugins` without a separate plugin-install step and executes its program inside argocd-repo-server when a helmCharts repository URL uses the plugin's protocol. The command runs as the repo-server user and can read repository credentials and other process-accessible data. An attacker can commit the Kustomization and plugin to a Git repository that an Application builds or upload the files through POST /api/v1/applications/manifestsWithFiles, also exposed by argocd app diff --local --server-side-generate. The upload path requires only Application get permission on an existing Application, without Application update or sync permission or repository write access. Both delivery paths require prior operator enablement of --enable-helm; deployments that do not enable it are not affected. Kustomize 4.1.0 first passed helmGlobals.configHome through to Helm. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2.
