Technical details
A command injection vulnerability exists in the ms_service.pl service of StoneFly Storage Concentrator (SC) and Storage Concentrator Virtual Machine (SCVM). The service listens on TCP port 9000 by default and accepts custom network packets to perform device actions. Due to inadequate sanitization of these packets, an unauthenticated remote attacker can inject malicious payloads into OS commands. Successful exploitation allows for arbitrary command execution with root-level privileges. StoneFly recommends upgrading to version 8.0.4.29 or later to remediate this issue.
