  "account": "In the Java application ecosystem, two ports stand out for their prominence and potential security risks: port 7001 and port 7199. These ports have been associated with remote code execution vulnerabilities that can be exploited without requiring credentials.\n\nOn September 25, 2026, two queries were run to assess the prevalence of these ports. The first query, targeting port 7001, returned 3,331,906 matches. Port 7001 serves as the default HTTP listener for Oracle WebLogic Server, which is the administration console of the application server. If not configured correctly, this port can remain open and vulnerable.\n\nThe second query, targeting port 7199, yielded 1,037,743 matches. Port 7199 is the default JMX remote management port for Apache Cassandra, a database that holds the operational state of various dependent services. This port provides a management interface for the database.\n\nThe common thread between these ports is not the vendor, but the pattern of shipping default management listeners alongside the managed services on easily reachable ports. This architectural choice, while convenient during installation, contributes to the persistent exposure of management planes over time.\n\nNeither the port counts should be interpreted as a measure of vulnerability. Port 7001 is answered by WebLogic instances of every version and patch level, and other services may also bind to this port. Similarly, port 7199 is answered by Cassandra clusters regardless of their configuration. The real concern lies in the fact that these default management listeners are present on millions of publicly reachable addresses.\n\nFor organizations using Oracle WebLogic Server or Apache Cassandra, specific questions need to be addressed. Is the administration console on 7001 accessible from outside the administrative network? Is the JMX interface on 7199 protected or accepting unauthenticated connections from the same network as the application? Additionally, the patch status of the management plane should be checked separately from the application patch status. While middleware may be upgraded for business reasons, it often retains the original console configuration.\n\nFinally, it is crucial to monitor the admin interfaces for connections from unexpected sources. A management listener receiving traffic from outside its intended network is a finding, regardless of the application's own logs reporting no such activity.",
