Qué es el puerto 8009?

Port 8009 is the default port for Apache JServ Protocol (AJP), used to proxy requests from an Apache HTTP server to Apache Tomcat or other Java application servers. The Ghostcat vulnerability (CVE-2020-1938) allowed unauthenticated file reads and RCE through AJP, resulting in widespread exploitation of exposed port 8009.
