[原文]A cross-site-scripting (XSS) vulnerability exists when an open source customization for Microsoft Active Directory Federation Services (AD FS) does not properly sanitize a specially crafted web request to an affected AD FS server, aka "Open Source Customization for Active Directory Federation Services XSS Vulnerability." This affects Web Customizations.
Microsoft Web Customization for ADFS is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.
An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials or to perform unauthorized actions such as reading content on behalf of the victim within the context of the affected site.
Attackers can exploit this issue by enticing an unsuspecting user to follow a malicious URI.
