azure-file-csi-driver leaks service account tokens in the logs

Moderate severity GitHub Reviewed Published May 15, 2024 to the GitHub Advisory Database • Updated Jun 10, 2024

Package

gomod sigs.k8s.io/azurefile-csi-driver (Go)

Affected versions

Description

A security issue was discovered in azure-file-csi-driver where an actor with access to the driver logs could observe service account tokens. These tokens could then potentially be exchanged with external cloud providers to access secrets stored in cloud vault solutions. Tokens are only logged when TokenRequests is configured in the CSIDriver object and the driver is set to run at log level 2 or greater via the -v flag.

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.
