Parameter Value
CVSS 7.4 (HIGH)
Type CWE-295 (Improper Certificate Validation)
Vendor IBM
Public PoC No

IBM DataStage on Cloud Pak for Data 5.4.0.0 can allow a man-in-the-middle attacker to present a forged TLS certificate, intercept the connection, and capture the IAM bearer Authorization header automatically attached by the session adapter. The captured token grants full platform-scope tenant API access, enabling the attacker to read and manipulate the victim's DataStage projects, flows, assets, and pipeline definitions. This is client-side SDK code running on the user's own machine, so exploitation requires an external network interceptor rather than a co-tenant in the shared cluster.
