Since the vulnerability requires administrative privileges, limiting administrative access and monitoring privileged user activities may reduce risk until an official fix is available.

Description

IBM Cloud Pak for Data System versions 11.3.1.2 Interim Fix 001 through 11.3.1.2 Interim Fix 002 contain a vulnerability that allows users with administrative privileges to read and write arbitrary files due to incorrect permission assignments. This could lead to unauthorized data access and modification within the system.
