Vulnerability from cnvd - Published: 2021-01-22

Title

Loxone Miniserver授权问题漏洞

Description

Loxone Miniserver是美国Loxone公司的一个可对楼宇、房屋中设备、家居进行自动化提供能源管理、监控等功能的服务器。 Loxone Miniserver 11.1.9.3版本之前存在授权问题漏洞，该漏洞源于设备无法使用基于“升级包签名”的身份验证方法，这些设备可以在未确定的时间段内继续使用未经身份验证的云服务。一旦单个设备的固件更新，身份验证进行了一次，云服务就会重新对设备进行分类，以便随后总是需要身份验证，并且未能会发生欺骗。目前没有详细漏洞细节提供。

CVE-2020-27488 (GCVE-0-2020-27488)

Vulnerability from cvelistv5 – Published: 2021-01-13 19:06 – Updated: 2024-08-04 16:18

Summary

Loxone Miniserver devices with firmware before 11.1 (aka 11.1.9.3) are unable to use an authentication method that is based on the "signature of the update package." Therefore, these devices (or attackers who are spoofing these devices) can continue to use an unauthenticated cloud service for an indeterminate time period (possibly forever). Once an individual device's firmware is updated, and authentication occurs once, the cloud service recategorizes the device so that authentication is subsequently always required, and spoofing cannot occur.

Severity

No CVSS data available.
