Hitachi Virtual Storage Platform E990, E1090…: Allocation of Resources Without Limits or Throttling

Published Updated By the CyberSecBulletin desk

CVE-2025-7737 is a high-severity allocation of resources without limits or throttling vulnerability in Hitachi Virtual Storage Platform E990, E1090, E1090H from Hitachi, with a CVSS 3.1 base score of 8.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions DKCMAIN Ver.93-07-21-80/00-05, CHB(iSCSI) Ver.88-01-02-04, DKCMAIN Ver.93-07-01-80/00-07, CHB(iSCSI) Ver.88-01-02-04, DKCMAIN Ver.93-06-82-80/00-06, CHB(iSCSI) Ver.88-01-02-04 as the first without the flaw, so updating Hitachi Virtual Storage Platform E990, E1090, E1090H to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.

The underlying weakness: Allocation of Resources Without Limits or Throttling

The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.

How developers prevent this class of flaw

  • Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
  • Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
