Storage Concentrator (SC & SCVM) contains a command injection vulnerability in the ms_service.pl service, which listens on TCP port 9000 by default and accepts custom network packets to perform device actions. An unauthenticated remote attacker can send a specially crafted packet containing a malicious payload that is processed without adequate sanitization, resulting in arbitrary command execution with root-level privileges.
