CVE-2020-23585Network attack vector

Router compromise via forged configuration upload

Published Nov 23, 2022 · Updated Apr 25, 2025

CSRF in OPTILINK OP-XT71000N hardware 2.2 with firmware OP_V3.3.1-191028 allows remote attackers to gain full privileges. The mgm_config_file.asp workflow accepts attacker-supplied XML at /boaform/admin/formMgmConfigUpload without sufficient CSRF protections. Exploitation requires user interaction and permits unauthorized configuration changes that can compromise the router and attached network.
