FreeIPA 中存在一个缺陷。未经认证的远程攻击者可以利用 FreeIPA/IdM 网页用户界面（Web UI）中密码重置页面的 DOM 型跨站脚本（XSS）漏洞。通过诱使受害者点击一个精心构造的链接并完成密码重置，攻击者可以注入并执行任意 JavaScript 代码。这使攻击者能够在受害者的已认证会话中执行操作；如果针对的是 IdM 管理员，攻击者甚至可能获得完全的管理员控制权。

Vulnerability Title
Freeipa: ipa: freeipa/idm: cross-site scripting vulnerability allows arbitrary code execution via crafted url
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in FreeIPA. An unauthenticated remote attacker could exploit a DOM Cross-Site Scripting (XSS) vulnerability in the FreeIPA/IdM Web UI password reset page. By enticing a victim to click a specially crafted link and complete a password reset, the attacker could inject and execute arbitrary JavaScript code. This allows the attacker to perform actions within the victim's authenticated session, potentially leading to full administrative control if an IdM administrator is targeted.
