Who should care

IBM Power Systems administrators, security teams, and users with access to BMC audit logs should be aware of this vulnerability and take necessary actions to mitigate it. They should review BMC firmware versions, monitor BMC audit logs for potential sensitive information exposure, and restrict access to BMC audit logs for admin users.

Technical summary

The vulnerability exists in IBM OPENBMC firmware versions FW1110.00 through FW1110.20 and FW1060.00 through FW1060.71. A user can supply a password with a resource dump request, which is stored in the BMC audit log. An admin user can view this password in the audit log. This could lead to potential sensitive information exposure.

Defensive priority

Medium priority due to potential for sensitive information exposure.

Recommended defensive actions

  • Inventory affected IBM Power Systems and review BMC firmware versions.
  • Apply vendor patches or updates for vulnerable firmware versions.
  • Monitor BMC audit logs for potential sensitive information exposure.
  • Restrict access to BMC audit logs for admin users.
  • Consider compensating controls such as additional logging and monitoring.

Evidence notes
