Title
Cruise-control: streams for apache kafka cruise control: authentication bypass via extra path segment allows unauthenticated access to all admin endpoints
Summary
Cruise Control's Jetty ConstraintSecurityHandler registers security constraints on exact path specs without a catch-all wildcard constraint and without calling setDenyUncoveredHttpMethods(true). The servlet routes requests using Path.of(pathInfo).getFileName(), which strips all leading segments and trailing slashes. Requests like POST /kafkacruisecontrol/x/rebalance bypass authentication entirely but still dispatch to admin endpoints. All 15 admin endpoints become reachable without authentication. In AMQ Streams, the Strimzi operator's NetworkPolicy restricts Cruise Control port 9090 to operator pods only, reducing effective severity to Important.
