CVE-2016-8942 IBM CVE debrief

Who should care

Administrators and security teams responsible for IBM Tivoli Storage Productivity Center or IBM Spectrum Control deployments should review this issue, especially where multiple authenticated users have access to administrative or operational functions.

Technical summary

NVD classifies the weakness as CWE-284 (Improper Access Control) with CVSS v3.0 vector AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N. The described impact is limited to unauthorized changes to a narrow set of server properties by an authenticated user who has intimate knowledge of the system. NVD also links an IBM PSIRT advisory and a SecurityFocus entry, and lists multiple affected IBM TSPC/Spectrum Control versions.

Defensive priority

Low immediate urgency, but it should be handled in normal vendor patching and access-control review cycles for any affected IBM deployment.

Recommended defensive actions

• Inventory IBM Tivoli Storage Productivity Center and IBM Spectrum Control instances and compare installed versions against the affected versions listed in the NVD record.
• Review the IBM PSIRT advisory referenced by NVD for vendor remediation guidance and apply the recommended update or mitigation.
• Restrict access to authenticated accounts that can administer or alter server properties, and periodically review those accounts.
• Audit property-change activity on affected servers and alert on unexpected configuration edits.
• If the product is still in use, plan a supported upgrade path; if it is not, prioritize migration off the affected software.
