CVE-2024-8038: Vulnerable juju introspection abstract UNIX domain socket
(updated )
An abstract UNIX domain socket responsible for introspection is available without authentication locally to any user with access to the network namespace where the local juju agent is running.
On a juju controller agent, denial of service can be performed by using the /leases/revoke
endpoint. Revoking leases in juju can cause availability issues.
On a juju machine agent that is hosting units, disabling the unit component can be performed using the /units
endpoint with a “stop” action.
