Detailsinfo

A vulnerability classified as very critical was found in StoneFly Storage Concentrator and Storage Concentrator Virtual Machine. Affected by this vulnerability is some unknown processing of the file ms_service.pl of the component Packet Handler. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at cisa.gov. This vulnerability is known as CVE-2026-56413 since 06/22/2026. The exploitation appears to be easy. The attack can be launched remotely.
