Argoproj: Security Vulnerabilities
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to versions 2.13.8, 2.14.13, and 3.0.4, an attacker can perform arbitrary actions on behalf of the victim via the API. Due to the improper filtering of URL protocols in the repository page, an attacker can achieve cross-site scripting with permission to edit the repository. This issue has been patched in versions 2.13.8, 2.14.13, and 3.0.4.

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. A vulnerability was discovered in Argo CD that exposed secret values in error messages and the diff view when an invalid Kubernetes Secret resource was synced from a repository. The vulnerability assumes the user has write access to the repository and can exploit it, either intentionally or unintentionally, by committing an invalid Secret to repository and triggering a Sync. Once exploited, any user with read access to Argo CD can view the exposed secret data. The vulnerability is fixed in v2.13.4, v2.12.10, and v2.11.13.

Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. When using `--auth-mode=client`, Archived Workflows can be retrieved with a fake or spoofed token via the GET Workflow endpoint: `/api/v1/workflows/{namespace}/{name}` or when using `--auth-mode=sso`, all Archived Workflows can be retrieved with a valid token via the GET Workflow endpoint: `/api/v1/workflows/{namespace}/{name}`. No authentication is performed by the Server itself on `client` tokens. Authentication & authorization is instead delegated to the k8s API server. However, the Workflow Archive does not interact with k8s, and so any token that looks valid will be considered authenticated, even if it is not a k8s token or even if the token has no RBAC for Argo. To handle the lack of pass-through k8s authN/authZ, the Workflow Archive specifically does the equivalent of a `kubectl auth can-i` check for respective methods. In 3.5.7 and 3.5.8, the auth check was accidentally removed on the GET Workflow endpoint's fallback to archived workflows on these lines, allowing archived workflows to be retrieved with a fake token. This vulnerability is fixed in 3.6.2 and 3.5.13.

Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. Due to a race condition in a global variable in 3.6.0-rc1, the argo workflows controller can be made to crash on-command by any user with access to execute a workflow. This vulnerability is fixed in 3.6.0-rc2.

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD has a Web-based terminal that allows users to get a shell inside a running pod, just as they would with kubectl exec. Starting in version 2.6.0, when the administrator enables this function and grants permission to the user `p, role:myrole, exec, create, */*, allow`, even if the user revokes this permission, the user can still perform operations in the container, as long as the user keeps the terminal view open for a long time. Although the token expiration and revocation of the user are fixed, however, the fix does not address the situation of revocation of only user `p, role:myrole, exec, create, */*, allow` permissions, which may still lead to the leakage of sensitive information. A patch for this vulnerability has been released in Argo CD versions 2.11.7, 2.10.16, and 2.9.21.

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. This report details a security vulnerability in Argo CD, where an unauthenticated attacker can send a specially crafted large JSON payload to the /api/webhook endpoint, causing excessive memory allocation that leads to service disruption by triggering an Out Of Memory (OOM) kill. The issue poses a high risk to the availability of Argo CD deployments. This vulnerability is fixed in 2.11.6, 2.10.15, and 2.9.20.

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It has been discovered that an unprivileged pod in a different namespace on the same cluster could connect to the Redis server on port 6379. Despite having installed the latest version of the VPC CNI plugin on the EKS cluster, it requires manual enablement through configuration to enforce network policies. This raises concerns that many clients might unknowingly have open access to their Redis servers. This vulnerability could lead to Privilege Escalation to the level of cluster controller, or to information leakage, affecting anyone who does not have strict access controls on their Redis instance. This issue has been patched in version(s) 2.8.19, 2.9.15 and 2.10.10.
