漏洞描述

SoftNAS Cloud是美国SoftNAS公司的一套软件定义的NAS文件管理系统。该系统主要用于提供企业级NAS功能，包括加密、快照和自动故障转移等功能。 SoftNAS Cloud 4.2.0版本和4.2.1版本中存在安全漏洞。远程攻击者可利用该漏洞创建新的用户或以管理权限执行任意命令。

SoftNAS Cloud 4.2.0 and 4.2.1 allows remote command execution. The NGINX default configuration file has a check to verify the status of a user cookie. If not set, a user is redirected to the login page. An arbitrary value can be provided for this cookie to access the web interface without valid user credentials. If customers have not followed SoftNAS deployment best practices and expose SoftNAS StorageCenter ports directly to the internet, this vulnerability allows an attacker to gain access to the Webadmin interface to create new users or execute arbitrary commands with administrative privileges, compromising both the platform and the data.
