CVE-2026-56413
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedStorage 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceStorage Concentrator (SC & SCVM) contains an unauthenticated command injection vulnerability in the ms_service.pl service listening on TCP port 9000. The service processes custom network packets containing device actions without sanitizing the input, allowing an attacker to inject and execute arbitrary commands with root privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if ms_service.pl process is runningRun 'ps aux | grep ms_service.pl' or 'systemctl status ms_service' to verify the service is activeAffected if The ms_service.pl process is running and listening on port 9000
-
Verify TCP port 9000 is listeningRun 'netstat -tlnp | grep 9000' or 'ss -tlnp | grep 9000' to confirm the service is bound to the networkAffected if Port 9000 is open and bound to a network interface (0.0.0.0 or external IP)
-
Identify the Storage Concentrator versionCheck the product documentation, run 'rpm -q storage-concentrator' or 'dpkg -l | grep storage-concentrator', or look for version files in /opt/SC or /usr/local/SCAffected if The installed version falls within any vulnerable version range (compare against vendor release notes for CVE-2026-56413)
-
Confirm the service lacks authenticationInspect the ms_service.pl configuration files in /etc/SC or the product config directory for authentication settings, or test if unauthenticated packets can be sent to port 9000Affected if No authentication or authorization mechanism is configured for the ms_service.pl service
You are affected if the Storage Concentrator ms_service.pl is running on port 9000 and accessible over the network without authentication controls, allowing unauthenticated attackers to inject commands.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and sanitization on all packet data processed by ms_service.pl, or add authentication/authorization controls to the service. Network-level controls such as restricting access to port 9000 to trusted IPs can serve as an interim measure.
