'Name' => 'Apache RocketMQ update config RCE',
'Description' => %q{
RocketMQ versions 5.1.0 and below are vulnerable to Arbitrary Code Injection. Broker component of RocketMQ is
leaked on the extranet and lack permission verification. 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.
