CVE-2022-36407

Password disclosure via plaintext diagnostic logs

Published Mar 25, 2024 · Updated Aug 3, 2024

Plaintext password storage in Hitachi disk-array log files allows local users to obtain sensitive credentials from affected systems. The logging path writes passwords to diagnostic log files without protecting their confidentiality. Access requires an authenticated array login to collect the logs, limiting exposure to users who can invoke log collection or obtain its output.
