Users with Overall/Read access can enumerate credential IDs in Pipeline GitHub Notify Step Plugin

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

Package

maven org.jenkins-ci.plugins:pipeline-build-step (Maven)

Affected versions

< 1.0.5

Patched versions

1.0.5

Description

Pipeline GitHub Notify Step Plugin 1.0.4 and earlier provides a list of applicable credential IDs to allow users configuring the plugin to select the one to use.

This functionality does not correctly check permissions, allowing any user with Overall/Read permission to get a list of valid credentials IDs. Those can be used as part of an attack to capture the credentials using another vulnerability.

An enumeration of credentials IDs in Pipeline GitHub Notify Step Plugin 1.0.5 requires the permission to configure a project.

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.
