CVE-2024-38437Network attack vector

Unauthenticated access to sensitive internal routes

Published Jul 21, 2024 · Updated Aug 2, 2024

Authentication bypass in D-Link DSL-225 firmware BZ_1.00.16 allows remote attackers to access sensitive internal routes without credentials. The affected routes accept requests without enforcing authentication, but D-Link has not published their names or implementation locus. Network access to the router is required, and published material does not delimit which elevated features those routes expose.
