CVE-2024-28247Public exploitNetwork attack vector

Authenticated privileged file read via local adlists

Published Mar 27, 2024 · Updated Aug 13, 2024

Arbitrary file read in Pi-hole before 5.18 allows remote authenticated users to disclose privileged server files through an adlist. The gravity_DownloadBlocklistFromUrl function follows a file:// adlist as root, and gravity processing returns the first five non-domain lines in the web interface. Access to the administration interface is required; readable content can include password hashes and other sensitive local data.
