DescriptionCVE.org

A command injection remote code execution vulnerability exists in HPE StoreOnce Software.

Executive ViewAI

Why It Matters

CVE-2025-37089 is a critical command injection vulnerability in HPE StoreOnce backup storage software (CVSS 9.8) that enables remote code execution without authentication, directly compromising backup integrity and potentially enabling lateral movement into protected environments. Organizations using StoreOnce must treat this as a priority security incident affecting data protection and recovery capabilities.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not possible: implement network segmentation to restrict access to StoreOnce management interfaces to trusted administrative networks only, disable remote management protocols where operationally viable, and monitor all StoreOnce inbound connections for suspicious command patterns or failed authentication attempts.
