Summary
IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to execute arbitrary code due to improper neutralization of special elements used in an OS command.
Risk Assessment
An authenticated attacker could take control of the system, execute arbitrary commands, and access processed data. This may lead to full compromise of the DataStage environment.
Recommendation
Immediately apply available security patches for IBM DataStage on Cloud Pak for Data 5.4.0.0. Additionally, restrict privileges of authenticated accounts and monitor for unusual OS commands.
