Technical Analysis

This vulnerability (CVE-2025-7737) concerns improper resource allocation controls (CWE-770) in the 10G iSCSI interface of Hitachi Virtual Storage Platform models including E990, E1090, E1090H, E390, E590, E790, G130, G150, G350, G370, G700, G900, VX8, VX7, and others. The issue allows denial of service by exhausting resources due to lack of limits or throttling. Affected versions are those with DKCMAIN and CHB(iSCSI) software versions prior to several specified release versions, but exact affected version ranges are not explicitly enumerated in a canonical form. The vulnerability has a CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H), indicating network exploitable, no privileges or user interaction required, scope changed, no confidentiality or integrity impact, but high impact on availability. No vendor advisory or patch information is provided, and no known exploits in the wild have been reported.

Potential Impact

Successful exploitation of this vulnerability can cause denial of service by exhausting resources on the affected Hitachi Virtual Storage Platform devices via the 10G iSCSI interface. This results in disruption of availability of storage services without impacting confidentiality or integrity.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, users should monitor Hitachi's advisories for updates. No vendor-provided mitigations or workarounds are currently documented.
