Jenkins Stored Cross-site Scripting vulnerability

High severity GitHub Reviewed Published Jul 26, 2023 to the GitHub Advisory Database • Updated Nov 7, 2023

Package

maven org.jenkins-ci.main:jenkins-core (Maven)

Affected versions

< 2.401.3
= 2.415
>= 2.402, < 2.414.1

Patched versions

2.401.3
2.416
2.414.1

Description

Jenkins applies formatting to the console output of builds, transforming plain URLs into hyperlinks. Jenkins 2.415 and earlier, 2.414 and earlier, and LTS 2.401.2 and earlier does not sanitize or properly encode URLs of these hyperlinks in build logs. This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control build log contents. Jenkins 2.416, 2.414.1, and LTS 2.401.3 encodes URLs of affected hyperlink annotations in build logs.

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.
