Hitachi Virtual Storage Platform E390, E590…: Missing Authorization

Published Updated By the CyberSecBulletin desk

CVE-2025-2902 is a high-severity missing authorization vulnerability in Hitachi Virtual Storage Platform E390, E590, E790, E990, E1090, E390H, E590H, E790H, E1090H from Hitachi, with a CVSS 3.1 base score of 8.3 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version DKCMAIN Ver. 93-07-26-xx/00, GUM Ver. 93-07-26/00 as the first without the flaw, so updating Hitachi Virtual Storage Platform E390, E590, E790, E990, E1090, E390H, E590H, E790H, E1090H to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.

The underlying weakness: Missing Authorization

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.

How developers prevent this class of flaw

  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries. Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
  • Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using authorization frameworks such as the JAAS Authorization Framework and the OWASP ESAPI Access Control feature.
