Path Traversal vulnerability in Jenkins Embeddable Build Status Plugin

Moderate severity GitHub Reviewed Published Jun 24, 2022 to the GitHub Advisory Database • Updated Jan 31, 2023

Package

maven org.jenkins-ci.plugins:embeddable-build-status (Maven)

Affected versions

< 2.0.4

Patched versions

2.0.4

Description

Jenkins Embeddable Build Status Plugin 2.0.3 and earlier allows specifying a style query parameter that is used to choose a different SVG image style without restricting possible values, resulting in a relative path traversal vulnerability that allows attackers without Overall/Read permission to specify paths to other SVG images on the Jenkins controller file system.

Embeddable Build Status Plugin 2.0.4 restricts the style query parameter to one of the three legal values.

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.
