## Technical details

A path traversal vulnerability (CWE-22) in IBM DataStage on Cloud Pak for Data allows a remote authenticated attacker to craft malicious input that traverses directory boundaries and access unintended files or directories, resulting in denial of service. The vulnerability requires valid authentication credentials and network access to the DataStage service. By exploiting the improper validation of file paths, an attacker can trigger a condition that crashes or stops the service. The vulnerability affects version 5.4.0.0 and patches or fixes should be obtained from IBM's support channels.
