How the attack works simplified

  1. 1Attacker on networkSends spoofed login identity
  2. 2Request reaches HiRDBServer accepts the forged identity
  3. 3Authentication skippedSpoofing bypasses the login check
  4. 4Database access gainedAttacker reads or changes data
  5. ResultAttacker gets unauthorized database access

What happened

An authentication bypass by spoofing flaw exists in HiRDB Server across versions 10, 9, 9 with additional function, and 9(32), allowing an attacker to impersonate a legitimate party to gain access.

Why it is dangerous: A successful attacker could access or change data stored in the HiRDB database and take control of the server's operations. Organizations running these older HiRDB versions are at risk, with a CVSS score of 9.8 (critical).

Are you affected?

You are affected if you run HiRDB Server Version 10 before 10-12-01, or HiRDB Server Version 9 (09-00 through 09-66-22), HiRDB Server with Additional Function Version 9 (09-00 through 09-66/V), or HiRDB Server Version 9(32) (09-02 through 09-66-22) or with Additional Function (09-00 through 09-66-/V).

HiRDB Server Version 10: 10-00 before 10-12-01; HiRDB Server Version 9: 09-00 through 09-66-22; HiRDB Server with Additional Function Version 9: 09-00 through 09-66/V; HiRDB Server Version 9(32): 09-02 through 09-66-22; HiRDB Server with Additional Function Version 9(32): 09-00 through 09-66-/V

What to do

  1. Identify every HiRDB Server instance and its exact version.
  2. Update HiRDB Server Version 10 to 10-12-01 or later.
  3. Check the vendor advisory for fixed or mitigated builds of Version 9 and 9(32) installations, and apply them when available.
  4. Restrict network access to HiRDB servers until patched.
