CVE-2018-25111Public exploit

Attachment disclosure and tampering via zeroed umask

Published May 31, 2025 · Updated Jun 2, 2025

Insecure file permissions in django-helpdesk before 1.0.0 allow local users to read or modify ticket attachment data. The attachment_path logic in models.py calls os.umask(0) before creating attachment directories, leaving them mode 0777 and changing the process-wide mask for later files and directories. Any local account able to reach those filesystem paths can read or alter exposed attachment content without helpdesk authorization.
