CVE-2020-5549Network attack vector

Administrator action forgery via malicious web page

Published Apr 8, 2020 · Updated Aug 4, 2024

Cross-site request forgery in Plat'Home EasyBlocks IPv6 2.0.1 and earlier allows remote attackers to perform unintended administrator operations. A malicious page viewed during an administrator's management-console session causes the browser to submit unauthorized requests, but the affected endpoints and missing request validation are undisclosed. The attack requires the administrator to view attacker-controlled content while logged in; the resulting actions are limited by that administrator's console privileges.
