Incorrect permission checks in Jenkins Support Core Plugin

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

Package

maven org.jenkins-ci.plugins:support-core (Maven)

Affected versions

<= 1206.v14049fa

Patched versions

1206.1208.v9b_7a_1d48db_0f

Description

Support Core Plugin defines the permission Support/DownloadBundle that allows users without Overall/Administer permission to create and download support bundles containing a limited set of diagnostic information.

Support Core Plugin 1206.v14049fa_b_d860 and earlier does not correctly perform permission checks in several HTTP endpoints.

This allows attackers with Support/DownloadBundle permission to download a previously created support bundle containing information limited to users with Overall/Administer permission.

Support Core Plugin 1206.1208.v9b_7a_1d48db_0f deprecates the Support/DownloadBundle permission. The Overall/Administer permission is now required to download support bundles.

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.
