Missing permission check in Jenkins Project Inheritance Plugin

Moderate severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Oct 26, 2023

Package

maven hudson.plugins:project-inheritance (Maven)

Affected versions

<= 21.04.03

Patched versions

None

Description

Jenkins limits access to job configuration XML data (config.xml) to users with Job/ExtendedRead permission, typically implied by Job/Configure permission. Project Inheritance Plugin has several job inspection features, including the API URL /job/…​/getConfigAsXML for its Inheritance Project job type that does something similar.

Project Inheritance Plugin 21.04.03 and earlier does not check permissions for this new endpoint, granting access to job configuration XML data to every user with Job/Read permission.

Additionally, the encrypted values of secrets stored in the job configuration are not redacted, as they would be by the config.xml API for users without Job/Configure permission.

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.
