OpenFeature Operator vulnerable to Cluster-level Privilege Escalation

High severity GitHub Reviewed Published Apr 12, 2023 in open-feature/open-feature-operator • Updated Apr 25, 2023

Package

gomod github.com/open-feature/open-feature-operator (Go)

Affected versions

< 0.2.32

Patched versions

0.2.32

Description

Impact

On a node controlled by an attacker or malicious user, the lax permissions configured on open-feature-operator-controller-manager can be used to further escalate the privileges of any service account in the cluster.

The increased privileges could be used to modify cluster state, leading to DoS, or read sensitive data, including secrets.

Patches

The patch mitigates this issue by restricting the resources the open-feature-operator-controller-manager can modify.

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.
