CVE-2020-2254
MEDIUM5.3EPSS 2.4%Path traversal vulnerability in Blue Ocean Plugin
Published: 5/24/2022Modified: 2/16/2024
Description
Blue Ocean Plugin 1.23.2 and earlier provides an undocumented feature flag, `blueocean.features.GIT_READ_SAVE_TYPE`, that when set to the value `clone` allows an attacker with Item/Configure or Item/Create permission to read arbitrary files on the Jenkins controller file system. Blue Ocean Plugin 1.23.3 no longer includes this feature and redirects existing usage to a safer alternative.
