CVE-2025-37096 is a high-severity remote code execution vulnerability identified in Hewlett Packard Enterprise's (HPE) 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 v4.0 base score is 7.5, indicating a high level of risk. The vector details specify 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 scope remains unchanged (S:U), and there are no security requirements for confidentiality, integrity, or availability (SC:N, SI:N, SA:N). This suggests that once an attacker with high privileges and partial authentication access to the network can exploit this vulnerability without user interaction, they can execute arbitrary commands remotely, potentially compromising the entire system. 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 attackers to manipulate backup data, disrupt backup operations, or use the compromised system as a foothold for lateral movement within the network. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that organizations should prioritize monitoring and mitigation efforts to prevent exploitation once patches become available.

For European organizations, the impact of CVE-2025-37096 could be significant, especially for enterprises relying on HPE StoreOnce for critical backup and disaster recovery operations. Successful exploitation could lead to unauthorized command execution, resulting in data corruption, deletion, or theft of sensitive backup data. This could disrupt business continuity, cause data loss, and potentially expose confidential information protected under regulations such as GDPR. The high integrity and availability impact means that backup reliability could be compromised, affecting recovery capabilities after incidents. Additionally, attackers gaining control over backup infrastructure could use it as a pivot point to infiltrate other parts of the network, increasing the risk of widespread compromise. Given the partial authentication and high privilege requirements, insider threats or compromised administrative accounts could facilitate exploitation, emphasizing the need for strict access controls and monitoring. The absence of user interaction requirements means automated attacks could be feasible once the vulnerability is known and weaponized.

Specific mitigation steps include: 1) Immediately audit and restrict administrative and privileged access to HPE StoreOnce systems, ensuring the principle of least privilege is enforced. 2) Monitor network traffic and system logs for unusual command execution patterns or unauthorized access attempts targeting StoreOnce software. 3) Implement network segmentation to isolate backup infrastructure from general user networks and limit exposure to potential attackers. 4) Apply strict authentication mechanisms such as multi-factor authentication (MFA) for all privileged accounts accessing StoreOnce systems. 5) Prepare for patch deployment by establishing a rapid update process once HPE releases security patches addressing this vulnerability. 6) Conduct vulnerability scanning and penetration testing focused on command injection vectors within the backup environment. 7) Educate IT and security teams about the vulnerability specifics to enhance detection and response capabilities. 8) Consider deploying application-layer firewalls or intrusion prevention systems (IPS) capable of detecting and blocking command injection attempts targeting StoreOnce software interfaces.
