Jenkins GitHub Pull Request Builder Plugin

Low severity GitHub Reviewed Published May 14, 2022 to the GitHub Advisory Database • Updated Jan 28, 2023

Package

maven org.jenkins-ci.plugins:ghprb (Maven)

Affected versions

< 1.32.1

Patched versions

1.32.1

Description

GitHub Pull Request Builder Plugin stored the webhook secret shared between Jenkins and GitHub in plain text. This allowed users with Jenkins controller local file system access and Jenkins administrators to retrieve the stored password. The latter could result in exposure of the passwords through browser extensions, cross-site scripting vulnerabilities, and similar situations. GitHub Pull Request Builder Plugin 1.32.1 and newer stores the webhook secret encrypted on disk.

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.
