CVE-2025-37164 is a critical remote code execution vulnerability in HPE OneView that can be exploited by an unauthenticated remote attacker. HPE rates it as a CVSS 10.0 and lists impacted versions as HPE OneView, all versions through 10.20.
CISA added CVE-2025-37164 to the Known Exploited Vulnerabilities (KEV) catalog on January 7, 2026, indicating evidence of active exploitation and making this an urgent fix-and-verify priority.
Attack surface: HPE does not publish technical exploitation details in the bulletin. Rapid7 analysis indicates a REST API endpoint reachable without authentication may be involved.
Vulnerability type: Code injection leading to unauthenticated remote code execution.
Severity: CVSS 3.1 base score 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
A Rapid Response test for CVE-2025-37164 launched January 14, 2026. Rapid Response customers can use it to quickly validate exploitability across internal and internet-facing OneView instances and then confirm remediation after applying fixes.
Note: Third-party guidance commonly frames remediation as upgrading to a fixed major version (11.x) or applying the vendor hotfix. The vendor bulletin itself focuses on the security hotfix path.
| Indicator | Type | Description |
| Requests to high-risk OneView REST endpoints (example: /rest/id-pools/executeCommand) | Network / Web | HPE does not list endpoint IOCs in the bulletin. Rapid7’s analysis discusses REST endpoint exposure as a likely exploitation path; hunt for unusual REST calls from untrusted segments, unusual user agents, and requests containing command-injection patterns. |
| Unexpected process execution originating from OneView services | Host | Look for OneView web or API processes spawning shells, scripting engines, or system utilities atypical for the appliance baseline. |
| New or anomalous outbound connections from the OneView appliance | Network | Prioritize new destinations shortly after suspicious REST activity, especially infrastructure used for payload retrieval or interactive shells. |
