CVE-2023-53772Public exploitNetwork attack vector

Unauthenticated file disclosure via unrestricted about-page path

Published Dec 9, 2025 · Updated Apr 7, 2026

Path traversal in MiniDVBLinux 5.4 and earlier allows remote attackers to read arbitrary device files through the about page. The about-page handler accepts the file GET parameter as a filesystem path and returns the selected file between preformatted response tags without restricting it to an allowed directory. No authentication or user interaction is required; a crafted request can expose sensitive system data but does not modify files or interrupt service.
