Vulnerability Title
Path Traversal Vulnerability in LabOne User Interface
Source: NVD (National Vulnerability Database)
Vulnerability Description
The LabOne Web Server, backing the LabOne User Interface, contains insufficient input validation in its file access functionality. An unauthenticated attacker could exploit this vulnerability to read arbitrary files on the host system that are accessible to the operating system user running the LabOne software. Additionally, the Web Server does not sufficiently restrict cross-origin requests, which could allow a remote attacker to trigger file access from a victim's browser by directing the victim to a malicious website. The vulnerability is only exploitable when the LabOne Web Server is running. Installations using only the LabOne APIs without starting the Web Server are not exposed.

Zurich Instruments LabOne Web Server 路径遍历漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Zurich Instruments LabOne Web Server是瑞士Zurich Instruments公司的一个提供仪器控制、数据采集与可视化操作界面的网页服务组件。 Zurich Instruments LabOne Web Server存在路径遍历漏洞，该漏洞源于文件访问功能输入验证不足，允许未经身份验证的攻击者读取主机系统上LabOne软件运行用户可访问的任意文件。此外，Web服务器未充分限制跨域请求，可能允许远程攻击者通过将受害者引导至恶意网站来触发文件访问。
