CVE-2020-2171

描述

RapidDeploy Plugin 4.2 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks. This allows a user able to control the input files for the 'RapidDeploy deployment package build' build or post-build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller, server-side request forgery, or denial-of-service attacks. RapidDeploy Plugin 4.2.1 disables external entity resolution for its XML parser.
