CVE-2023-31677Network attack vector

Alarm-device data disclosure via altered eseeid

Published May 16, 2023 · Updated Jan 23, 2025

Improper access control in Luowice 3.5.18 allows remote attackers to view information from other alarm devices by changing eseeid. The alarm-device information request accepts a modified eseeid parameter without enforcing permission to access the referenced device. Network access is sufficient, and exploitation discloses another alarm device's information without reported modification or service interruption.
