Severity

Medium

Vendor

VMware Tanzu

Description

VMware Tanzu Application Service for VMs (2.7.x versions prior to 2.7.19, 2.8.x versions prior to 2.8.13, and 2.9.x versions prior to 2.9.7) contains an App Autoscaler that logs the UAA admin password. This credential is redacted on VMware Tanzu Operations Manager; however, the unredacted logs are available to authenticated users of the BOSH Director. This credential would grant administrative privileges to a malicious user.

The same versions of App Autoscaler also log the App Autoscaler Broker password. Prior to newer versions of Operations Manager, this credential was not redacted from logs. This credential allows a malicious user to create, delete, and modify App Autoscaler services instances. Operations Manager started redacting this credential from logs as of its versions 2.7.15, 2.8.6, and 2.9.1.

Note that these logs are typically only visible to foundation administrators and operators.
