CVE-2023-41721Network attack vector

Device configuration disclosure via improper adoption controls

Published Oct 25, 2023 · Updated Sep 13, 2024

Improper access control in Ubiquiti UniFi Network Application 7.5.176 and earlier allows remote attackers to access device configuration information. The device-adoption workflow applies improper access-control logic when returning configuration information, but Ubiquiti has not disclosed the faulty check. The vulnerable deployment must run on a listed UniFi Gateway Console, and the attacker must already have network access; only configuration-information access is confirmed.
