Description
N-able N-central before 2026.3.1.14 uses a session-scoped Struts form on an unauthenticated action. Two concurrent multipart requests can race the form's multipart handler and expose Jetty's live configuration to Commons BeanUtils property population.
This module changes a lazy N-central servlet holder into Jetty's bundled CGI servlet, configures it to invoke /bin/sh, and sends a command payload through the holder's existing URL mapping. By default, a second CGI request uses N-central's local JMX service and installed Java libraries to stop only the changed holder and restore its original servlet in memory.
