VMWare Aria Operations for Networks (vRealize Network Insight) is vulnerable to command injection when accepting user input through the Apache Thrift RPC interface. This vulnerability allows a remote unauthenticated attacker to execute arbitrary commands on the underlying operating system as the root user. The RPC interface is protected by a reverse proxy which can be bypassed. VMware has evaluated the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.
a malicious actor can get remote code execution in the context of 'root' on the appliance.
