Open redirect vulnerability in Microsoft Forefront Unified Access Gateway (UAG) 2010 SP1 and SP1 Update 1 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a crafted URL, aka "UAG Blind HTTP Redirect Vulnerability."
Vulnerable Systems:
* Microsoft Forefront Unified Access Gateway (UAG) 2010 SP1 and SP1 Update 1
A spoofing vulnerability exists in Forefront Unified Access Gateway (UAG) that could lead to information disclosure. The vulnerability could allow spoofing by redirecting web traffic intended for the UAG server to a malicious website. To exploit the vulnerability, an attacker could send a link that has a specially crafted URL to a user of a UAG server, and convince the user to click the link. When an authenticated UAG user clicks the link, the authenticated user's browser session could be redirected to a malicious site that is designed to impersonate a legitimate UAG web interface. By doing so, the attacker could trick the user and potentially acquire sensitive information, such as the user's credentials
