CVE-2020-2234

Description

Pipeline Maven Integration Plugin 3.8.2 and earlier does not perform a permission check in a method implementing form validation. This allows users with Overall/Read access to Jenkins to connect to an attacker-specified JDBC URL using attacker-specified credentials IDs obtained through another method, potentially capturing credentials stored in Jenkins. Additionally, this form validation method does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. Pipeline Maven Integration Plugin 3.8.3 requires POST requests and Job/Configure permission for the affected form validation method.
