## Overview

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 assign overly permissive operating-system permissions to certain log files, which could allow a local user to read or alter log data. The corrected default permissions apply to newly created and rotated logs; existing logs retain their current permissions until remediated.

## Remediation
