Lack of authentication mechanism for webhook in CloudBees Docker Hub/Registry Notification Plugin

Moderate severity GitHub Reviewed Published Nov 16, 2022 to the GitHub Advisory Database • Updated Jan 5, 2024

Package

maven org.jenkins-ci.plugins:dockerhub-notification (Maven)

Affected versions

<= 2.6.2

Patched versions

2.6.2.1

Description

CloudBees Docker Hub/Registry Notification Plugin provides several webhook endpoints that can be used to trigger builds when Docker images used by a job have been rebuilt.

In CloudBees Docker Hub/Registry Notification Plugin 2.6.2 and earlier, these endpoints can be accessed without authentication.

This allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified repository.

CloudBees Docker Hub/Registry Notification Plugin 2.6.2.1 requires a token as a part of webhook URLs, which will act as authentication for the webhook endpoint. As a result, all webhook URLs in the plugin will be different after updating the plugin.

Administrators can set the Java system property org.jenkinsci.plugins.registry.notification.webhook.JSONWebHook.DO_NOT_REQUIRE_API_TOKEN to true to disable this fix.

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.
