HighCVSS 8.8Exploitation Probability (EPSS)
Elevated risk59th percentile - higher than 59% of all known CVEs
Summary
IBM DataStage on Cloud Pak for Data 5.4.0.0 is vulnerable to OS command injection. A remote authenticated attacker could exploit this to execute arbitrary commands.
Risk Assessment
The ability for an authenticated user to run arbitrary commands remotely creates a risk of server takeover and unauthorized access to processed data.
Recommendation
Promptly apply the IBM fix for Cloud Pak for Data 5.4.0.0 and review permissions of accounts with DataStage access.
