Helm OCI credentials leaked into Argo CD logs

Moderate
alexmt published GHSA-6w87-g839-9wv7 Mar 8, 2021

Package

Argo CD

Affected versions

All versions prior to 1.7.14 and 1.8.7

Patched versions

1.7.14, 1.8.7

Description

Impact

When Argo CD was connected to a Helm OCI repository with authentication enabled, the credentials used for accessing the remote repository were logged.

Anyone with access to the pod logs - either via access with appropriate permissions to the Kubernetes control plane or a third party log management system where the logs from Argo CD were aggregated - could have potentially obtained the credentials to the Helm OCI repository.

If you are using Helm OCI repositories with Argo CD, it is strongly recommended to upgrade Argo CD to the latest patch version and to change the credentials used to access the repositories.

Patches

A patch for this vulnerability is available with the v1.8.7 and v1.7.14 releases of Argo CD.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
