Lack of type validation in agent related REST API in Jenkins
🔗 CVE IDs covered (1)
📋 Description
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.
