CVE-2023-32148

Authentication bypass via crafted PrivateLogin XML

Published May 3, 2024 · Updated Sep 18, 2024

Authentication bypass in D-Link DIR-2640 firmware 1.11B02 and earlier allows remote attackers on an adjacent network to log in. The HNAP PrivateLogin handler accepts a crafted XML element in a login request and marks authentication successful without valid credentials. Access requires reachability to default TCP port 80; the bypass grants authenticated management control, with no reported data disclosure or service interruption.
