Executive ViewAI

Why It Matters

CVE-2025-37090 is a critical SSRF vulnerability in HPE StoreOnce backup storage software that could allow attackers to bypass network controls and access internal resources, potentially compromising backup integrity and exposing sensitive data across backup infrastructure. Organizations relying on StoreOnce for backup operations face immediate risk to data protection posture and require urgent remediation.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not feasible, implement network segmentation to restrict StoreOnce system outbound connectivity to only required backup targets and management servers, and implement strict firewall rules limiting access to StoreOnce administrative interfaces to authorized networks only.
