Vulnerability Title
MajorDoMo Stored Cross-Site Scripting via Property Set Endpoint
Source: NVD (National Vulnerability Database)
Vulnerability Description
MajorDoMo (aka Major Domestic Module) contains a stored cross-site scripting (XSS) vulnerability via the /objects/?op=set endpoint, which is intentionally unauthenticated for IoT device integration. User-supplied property values are stored raw in the database without sanitization. When an administrator views the property editor in the admin panel, the stored values are rendered without escaping in both a paragraph tag (SOURCE field) and a textarea element (VALUE field). The XSS fires on page load without requiring any click from the admin. Additionally, the session cookie lacks the HttpOnly flag, enabling session hijack via document.cookie exfiltration. An attacker can enumerate properties via the unauthenticated /api.php/data/ endpoint and poison any property with malicious JavaScript.

Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
MajorDoMo是MajorDoMo社区的一个开源DIY智能家居自动化平台。 MajorDoMo存在跨站脚本漏洞，该漏洞源于通过/objects/?op=set端点存储的用户提供的属性值未经清理原始存储在数据库中，当管理员在管理面板中查看属性编辑器时，存储的值在段落标签和textarea元素中未经转义渲染，可能导致存储型跨站脚本攻击和会话劫持。
