Technical impact
The vulnerability allows a remote authenticated attacker to execute arbitrary code on IBM DataStage on Cloud Pak for Data 5.4.0.0 through improper neutralization of special elements used in an OS command. This results in a classic remote code execution scenario, giving the attacker full control over the affected system and enabling compromise of confidentiality, integrity, and availability. The weakness corresponds to CWE‑94 (Improper Neutralization of Components in Dynamically Constructed Commands).
Affected Systems
IBM DataStage on Cloud Pak for Data, version 5.4.0.0, is susceptible. Users running this exact build should verify their installation.
Risk and Exploitability
The CVSS score of 8.8 indicates high severity, and while the EPSS score is currently unavailable, the absence of listing in the KEV catalog does not reduce the urgency. The vulnerability requires authentication but once credentials are in hand, an attacker can run arbitrary OS commands, implying a broad impact across the platform. The exploit path is straightforward: authenticate, submit a crafted input that is not properly escaped, and trigger command execution.
