Summary
IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to perform an arbitrary file write due to improper validation of file paths.
Risk Assessment
An authenticated attacker could overwrite or create arbitrary files on the server, potentially leading to code execution or data integrity loss.
Recommendation
Update IBM DataStage to a patched version and restrict service account privileges while verifying proper file path validation.
