CVE-2024-23898 Open this link in a new tabHow to fix?
Upgrade org.jenkins-ci.main:jenkins-core to version 2.426.3, 2.440.1, 2.442 or higher.
Overview
org.jenkins-ci.main:jenkins-core is an open source automation server.
Affected versions of this package are vulnerable to Origin Validation Error due to a lack of origin validation on the CLI WebSocket endpoint. An attacker can execute arbitrary CLI commands on the Jenkins controller by exploiting the cross-site WebSocket hijacking vulnerability.
Note:
Jenkins does not set an explicit SameSite attribute for session cookies. This can allow cross-site requests to make use of the session cookie, i.e., those requests are sent with the logged-in user’s authentication.
Workaround
Prevent WebSocket access using a reverse proxy
