The cPanel & WHM update-analysis system aggregates log files and system settings into a tarball that is sent to cPanel’s log processing servers. This opt-in service allows cPanel to detect trends in the errors that cPanel & WHM systems encounter. The tarballs generated by the update-analysis system are retained on the local file system, with 0644 permissions, inside a world-accessible directory and include copies of several sensitive log files. This allowed local users to view the sensitive data contained inside.
