Argo CD Insecure default administrative password

High severity GitHub Reviewed Published Jul 26, 2021 to the GitHub Advisory Database • Updated Aug 7, 2024

Package

Affected versions

<= 1.8.0

Patched versions

None

Description

In Argo CD versions 1.8.0 and prior, the default admin password is set to the argocd-server pod name. For insiders with access to the cluster or logs, this issue could be abused for privilege escalation, as Argo has privileged roles. A malicious insider is the most realistic threat, but pod names are not meant to be kept secret and could wind up just about anywhere.

Workaround:

The recommended mitigation as described in the user documentation is to use SSO integration. The default admin password should only be used for initial configuration and then disabled or at least changed to a more secure password.

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.
