The VMware Tanzu Application Service for VMs and Isolation Segment contain an information disclosure vulnerability due to the logging of credentials in hex encoding in platform system audit logs. A malicious non-admin user who has access to the platform system audit logs can access hex encoded CF API admin credentials and can push new malicious versions of an application. In a default deployment non-admin users do not have access to the platform system audit logs.

Weakness

Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.

Different log files may be produced and stored for:
