Severity ?

4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N

Summary

Lack of type validation in agent related REST API in Jenkins

Details

Jenkins 2.286 and earlier, LTS 2.277.1 and earlier does not validate the type of object created after loading the data submitted to the config.xml REST API endpoint of a node.

This allows attackers with Computer/Configure permission to replace a node with one of a different type.

Jenkins 2.287, LTS 2.277.2 validates the type of object created and rejects objects of unexpected types.
