CVE-2017-18752

Adjacent-network arbitrary file read

Published Apr 22, 2020 · Updated Aug 5, 2024

Arbitrary file read in NETGEAR EX and R series firmware allows attackers on an adjacent network to read device files without authentication. NETGEAR has not published the affected component, request path, or file-selection operation that exposes arbitrary files. Exploitation requires adjacent-network access and no authentication; NVD reports file confidentiality loss without integrity or availability impact.
