CVE-2025-2500Network attack vector

Unauthorized access via plaintext password storage

Published May 30, 2025 · Updated May 30, 2025

Plaintext password storage in Hitachi Energy Asset Suite 9.6.4.4 and 9.7 allows remote attackers to gain unauthorized access via SOAP Web services. Hitachi Energy maps the flaw to CWE-256 but does not identify the password-storage locus or disclose the SOAP operation that leaves credentials recoverable. Exploitation requires network access without prior privileges and attack-specific conditions, and it lengthens the period during which stored passwords can be attacked.
