HTTP: Microsoft Forefront Unified Access Gateway Signurl.asp Cross-Site Scripting

This signature detects attempts to exploit a known cross-site scripting vulnerability in Microsoft Forefront Unified Access Gateway (UAG). It is due to insufficient validation of user-supplied input in signurl.asp. A remote attacker can exploit this by enticing a target to open a malicious URL link. A successful attack can result in the compromise of Web browser cookies (including authentication cookies) associated with the site, and modification of user information.

Extended Description

Microsoft Forefront Unified Access Gateway 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 may help the attacker steal potentially sensitive information and launch other attacks.
