CVE-2020-9013Public exploitNetwork attack vector

Authenticated print-restriction bypass via watermark deletion

Published Feb 16, 2020 · Updated Aug 4, 2024

Improper input validation in Arvato Skillpipe 3.0 allows remote authenticated users to print course content without its intended watermark. The Web Reader relies on a client-side #watermark or print_watermark_wrapper DOM node that browser developer tools can delete before printing. Access to protected course content is required; the demonstrated consequence is unwatermarked printing, not broader content modification.
