Hitachi Virtual Storage Platform: Insertion of Sensitive Information into Log File

Published Updated By the CyberSecBulletin desk

CVE-2022-36407 is a critical-severity insertion of sensitive information into log file vulnerability in Hitachi Virtual Storage Platform from Hitachi, with a CVSS 3.1 base score of 9.9 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. 70-06-74-00/00, SVP Ver. 70-06-58/00 as the first without the flaw, so updating Hitachi Virtual Storage Platform to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.51% chance of exploitation within 30 days, which is low compared with other CVEs.

The underlying weakness: Insertion of Sensitive Information into Log File

The product writes sensitive information to a log file.

How developers prevent this class of flaw

  • Consider seriously the sensitivity of the information written into log files. Do not write secrets into the log files.
  • Remove debug log files before deploying the application into production.
  • Protect log files against unauthorized read/write.
