CVE-2026-16346: CWE-285 Improper Authorization in IBM DataStage on Cloud Pak for Data
CVE-2026-16346 is a critical vulnerability in IBM DataStage on Cloud Pak for Data version 5.4.0.0. It involves improper authorization that allows a remote authenticated attacker to execute arbitrary OS commands due to insufficient neutralization of special elements in commands. The vulnerability has a high CVSS score of 9.9, indicating severe impact on confidentiality, integrity, and availability.
AI Analysis
Technical Summary
IBM DataStage on Cloud Pak for Data 5.4.0.0 contains an improper authorization vulnerability (CWE-285) that permits a remote authenticated attacker to execute arbitrary operating system commands. This occurs because special elements used in OS commands are not properly neutralized, enabling command injection. The vulnerability is rated critical with a CVSS 3.1 score of 9.9, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and complete impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with valid authentication can execute arbitrary OS commands remotely, potentially leading to full system compromise including data theft, modification, or service disruption. The vulnerability affects confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Since this is not a cloud service, remediation depends on IBM releasing a fix. Until then, restrict access to authenticated users and monitor for suspicious activity. Check IBM's official advisory for updates on patch availability.
