Authenticated command execution via OS command injection
Published Sep 24, 2026 · Updated Sep 24, 2026
OS command injection in IBM DataStage on Cloud Pak for Data 5.4.0.0 allows remote authenticated users to execute arbitrary commands. IBM identifies improper neutralization of special elements in an OS command but does not disclose the affected endpoint, input, or code path. Access to an authenticated network interface is required, and successful exploitation executes commands in the DataStage service context.
