CVE-2018-16859
Description
Execution of Ansible content on Microsoft's Windows platform with Powershell 5 or higher may disclose sensitive execution details including 'become' passwords, Ansible module arguments, and return values via Powershell's 'suspicious scriptblock logging' feature, which is enabled by default. The details are logged to the Powershell Operational log, which is visible to all authenticated users by default.
Statement
CloudForms and Satellite 6 are not affected by this issue, since Microsoft Windows is not a supported platform.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
