CRITICAL 9.8

DescriptionCVE.org

A directory traversal information disclosure vulnerability exists in HPE StoreOnce Software.

Executive ViewAI

Why It Matters

HPE StoreOnce backup storage systems contain a critical directory traversal vulnerability (CVSS 9.8) that could allow attackers to access or modify sensitive backup data without authentication. This directly threatens backup integrity and recovery capabilities for organizations relying on StoreOnce for business continuity, potentially exposing restoration timelines and data confidentiality across backed-up systems.

Business Impact: Severe

Compensating Controls

Apply vendor patch. Until patched: restrict network access to StoreOnce management interfaces using firewall rules to trusted administrative networks only; disable remote access if not actively required; monitor backup system logs for directory traversal patterns (/../../ sequences); consider temporary failover to alternative backup storage if available.

Attack Technique

Path Traversal HIGH

Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
