Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

该 Web 界面在脚本上下文和超链接属性中反射了请求 URL 的一部分，且未进行充分的编码处理，同时无需身份验证即可访问。这使得未认证的网络攻击者可以构造一个链接，当用户访问该链接时，会在受影响的应用上下文中执行任意脚本，并可将用户的浏览器重定向到任意外部网站。成功利用此漏洞后，攻击者可以以被入侵用户的会话权限在应用内进行操作。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A web interface reflects a portion of the request URL into a script context and a hyperlink attribute without adequate encoding, and does not require authentication to reach. This allows an unauthenticated network attacker to craft a link that, when visited by a user, executes arbitrary script in the context of the affected application and can redirect the user's browser to an arbitrary external site. Successful exploitation could allow an attacker to act with the compromised user's session privileges within the application.
