IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to obtain sensitive information due to an absolute-path traversal vulnerability.

AnalysisAI

Absolute-path traversal in IBM DataStage on Cloud Pak for Data 5.4.0.0 allows a remote authenticated attacker to read sensitive files outside the intended directory scope, potentially exposing credentials, configuration data, or other platform secrets. The CVSS vector assigns C:H/I:H/A:H, though IBM's own description limits the stated impact to information disclosure - an inconsistency worth verifying with the vendor advisory. …

Vulnerability AssessmentAI

Exploitation Exploitation requires valid low-privilege user credentials on the IBM DataStage on Cloud Pak for Data 5.4.0.0 instance (PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 8.8 score reflects a network-reachable, low-complexity flaw requiring only low-privilege credentials (PR:L), which lowers the bar for exploitation significantly - even a mid-sized municipal IT team in inowroclaw operating a DataStage environment should treat this as urgent patching rather than a deferred risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Patch available per vendor advisory - apply the fix described at https://www.ibm.com/support/pages/node/7286562. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all instances of IBM DataStage running Cloud Pak for Data 5.4.0.0 in your environment and prioritize those containing sensitive data or connected to production systems. …
