Sources and claim methodology

  • Source referenceibm.com
Upstream source description

IBM DataStage on Cloud Pak for Data 5.4.0.0 allows an unauthenticated user to perform an arbitrary write into shared Redis under any tenant's key. This collapses the platform's credential-encryption boundary and lets an anonymous caller poison any tenant's cached flow parameters.
