CVE-2022-37930 is a security vulnerability identified in Hewlett Packard Enterprise (HPE) Nimble Storage Hybrid Flash Arrays and Nimble Storage Secondary Flash Arrays. The vulnerability allows for local disclosure of sensitive information, classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). Specifically, this issue affects versions prior to 5.2.1.900 (LTSR) and 5.3.0.0 (GA). The vulnerability requires local access with low privileges (PR:L) and user interaction (UI:R), and it has a high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The attack complexity is high (AC:H), indicating that exploitation is not trivial and requires specific conditions or knowledge. The CVSS v3.1 base score is 6.7, which is categorized as medium severity. The vulnerability does not appear to have known exploits in the wild as of the published date (November 3, 2022). The flaw could allow an attacker with local access to the storage array to disclose sensitive information, potentially leading to further compromise or data leakage. Given the nature of the affected products—enterprise-grade storage arrays used for critical data storage and backup—the exposure of sensitive information could have significant operational and security consequences. The vulnerability is mitigated by upgrading to versions 5.2.1.900 (LTSR) or 5.3.0.0 (GA) or later, though no direct patch links were provided in the source information.

For European organizations, the impact of CVE-2022-37930 can be substantial, particularly for enterprises relying on HPE Nimble Storage arrays for critical data storage, backup, and disaster recovery. Disclosure of sensitive information could lead to exposure of confidential business data, intellectual property, or personally identifiable information (PII), which may result in regulatory non-compliance under GDPR and other data protection laws. The integrity and availability impacts suggest that exploitation could also disrupt storage operations, potentially causing downtime or data corruption. This could affect sectors such as finance, healthcare, manufacturing, and government agencies that depend heavily on reliable and secure storage infrastructure. Since exploitation requires local access and user interaction, the threat is more relevant in environments where insider threats or compromised internal accounts exist. However, the high impact on confidentiality, integrity, and availability means that even limited exploitation could have cascading effects on business continuity and trust.

Upgrade affected HPE Nimble Storage Hybrid Flash Arrays and Secondary Flash Arrays to firmware versions 5.2.1.900 (LTSR) or 5.3.0.0 (GA) or later as soon as possible to remediate the vulnerability. Implement strict access controls and monitoring to limit local access to storage arrays only to authorized personnel, reducing the risk of local exploitation. Enforce multi-factor authentication (MFA) and strong credential management for all users with access to storage management interfaces to mitigate risks from compromised accounts. Conduct regular audits and monitoring of user activities on storage systems to detect unusual or unauthorized access attempts that could indicate exploitation attempts. Segment storage management networks from general user networks to reduce the likelihood of attackers gaining local access through lateral movement. Develop and test incident response plans specifically addressing storage infrastructure compromise scenarios to ensure rapid containment and recovery.
