CVE-2026-81548

8.8

IBM · DataStage on Cloud Pak for Data

IBM DataStage on Cloud Pak for Data 5.4.0.0 contains an OS command injection vulnerability, allowing authenticated remote attackers to execute arbitrary commands.

Executive summary

An OS command injection vulnerability in IBM DataStage on Cloud Pak for Data 5.4.0.0 poses a high risk of remote code execution for authenticated users.

Vulnerability

The software fails to properly neutralize special elements used in OS commands, resulting in a Command Injection (CWE-78) vulnerability. A remote attacker with authenticated access can leverage this flaw to execute arbitrary OS commands on the underlying system.

Business impact

The ability to execute arbitrary OS commands represents a critical security failure, as it allows attackers to bypass application-level controls entirely. With a CVSS score of 8.8, this vulnerability permits full system compromise, including unauthorized data access, modification, or complete service disruption, which could lead to significant reputational and operational damage.

Remediation

Immediate Action: Upgrade DataStage on Cloud Pak for Data to version 5.4 patch 7 or later by following the instructions provided in the official IBM documentation.

Proactive Monitoring: Review system and application logs for unusual command execution patterns or unexpected shell spawns originating from the DataStage service account.

Compensating Controls: Ensure that the application is running with the principle of least privilege, minimizing the permissions available to the service account to limit the potential impact of a successful command injection.

Exploitation status

Public Exploit Available: Unknown

Analyst recommendation

Given the high severity of this command injection vulnerability, administrators must prioritize the update to version 5.4 patch 7. Authenticated access is often a target for lateral movement, and immediate remediation is necessary to prevent potential exploitation by malicious actors.
