Descriptions

From Apache NiFi MiNiFi C++ version 0.5.0 the c2 protocol implements an "agent-update" command which was designed to patch the application binary. This "patching" command defaults to calling a trusted binary, but might be modified to an arbitrary value through a "c2-update" command. Said command is then executed using the same privileges as the application binary. This was addressed in version 0.10.0

Apache NiFi MiNiFi C++ versión 0.5.0, el protocolo c2 implementa un comando "agent-update" que fue diseñado para parchear el binario de la aplicación. Este comando de "patching" predeterminado llama a un binario confiable, pero puede ser modificado a un valor arbitrario mediante un comando "c2-update". Dicho comando es ejecutado entonces usando los mismos privilegios que el binario de la aplicación. Esto fue solucionado en versión 0.10.0.
