CVE-2025-37089 is a high-severity remote code execution vulnerability affecting Hewlett Packard Enterprise's StoreOnce Software. The vulnerability is classified as a command injection flaw (CWE-77), which allows an attacker to execute arbitrary commands on the affected system. The CVSS 4.0 vector indicates that the attack vector is network-based (AV:N), with low attack complexity (AC:L), but requires privileges (PR:H) and partial authentication (AT:P). No user interaction is needed (UI:N). The vulnerability impacts confidentiality, integrity, and availability at a high level (VC:H, VI:H, VA:H). The affected product, HPE StoreOnce Software, is a data backup and deduplication solution widely used in enterprise environments for efficient storage management. The vulnerability could allow an attacker with high privileges and partial authentication to execute arbitrary commands remotely, potentially leading to full system compromise, data theft, or disruption of backup services. No public exploits are currently known, and no patches have been published yet. The vulnerability was reserved in April 2025 and published in June 2025, indicating recent discovery. The lack of patches and known exploits suggests organizations should prioritize risk assessment and mitigation planning immediately.

For European organizations, the impact of this vulnerability could be significant, especially for those relying on HPE StoreOnce for critical backup and disaster recovery operations. Successful exploitation could lead to unauthorized access to sensitive backup data, disruption of backup processes, and potential ransomware deployment leveraging compromised backup infrastructure. This could result in data loss, operational downtime, and regulatory non-compliance, particularly under GDPR requirements for data protection and breach notification. The high privileges required reduce the risk somewhat but do not eliminate it, as insider threats or compromised credentials could enable exploitation. The availability of backup services is critical for business continuity; thus, disruption could have cascading effects on IT operations across sectors such as finance, healthcare, manufacturing, and government institutions in Europe.

Given the absence of patches, European organizations should implement immediate compensating controls. These include restricting network access to HPE StoreOnce management interfaces to trusted administrative networks only, employing strict access controls and multi-factor authentication to limit privileged user access, and monitoring for unusual command execution or system behavior indicative of exploitation attempts. Regularly auditing user privileges and reviewing authentication logs can help detect potential misuse. Network segmentation should isolate backup infrastructure from general IT networks to reduce attack surface. Organizations should also engage with HPE support channels to obtain any available security advisories or interim fixes. Preparing incident response plans specific to backup infrastructure compromise is advisable. Once patches are released, rapid deployment is critical. Additionally, organizations should consider enhanced logging and anomaly detection on backup systems to identify early signs of exploitation.
