CVE-2023-41187

Network-adjacent root code execution via unauthenticated HNAP

Published May 3, 2024 · Updated Aug 2, 2024

Missing authentication in the HNAP interface of D-Link DAP-1325 1.07b01 allows network-adjacent attackers to execute code as root. The interface exposes critical functionality without verifying a requester's identity before dispatching the requested operation. Access to the extender's adjacent network is required, but neither credentials nor user interaction is needed; successful exploitation grants full device control.
