CVE-2019-16271Network attack vector

Whiteboard PDF disclosure via unauthenticated web server

Published Jan 6, 2020 · Updated Aug 5, 2024

Information disclosure in DTEN D5 and D7 before 1.3.2 allows remote attackers to read saved whiteboard PDFs over TCP port 8080. An unauthenticated web server exposes files under storage/emulated/0/Notes/PDF without enforcing access control on document requests. Network reachability to port 8080 is sufficient, and the documented consequence is limited to disclosure of locally saved whiteboard PDFs.
