2.7.3- Upgrade ansible to this version or later
Description
Execution of Ansible playbooks on Windows platforms with PowerShell ScriptBlock logging and Module logging enabled can allow for 'become' passwords to appear in EventLogs in plaintext. A local user with administrator privileges on the machine can view these logs and discover the plaintext password. Ansible Engine 2.8 and older are believed to be vulnerable.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-532: Insertion of Sensitive Information into Log File
The product writes sensitive information to a log file.
How to prevent it
- Architecture and Design, Implementation: Consider seriously the sensitivity of the information written into log files. Do not write secrets into the log files.
- Distribution: Remove debug log files before deploying the application into production.
- Operation: Protect log files against unauthorized read/write.
- Implementation: Adjust configurations appropriately when software is transitioned from a debug state to production.
