Discussion
Community Server 'TagSelector.aspx' Cross Site Scripting Vulnerability
Community Server is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied data.
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 allow the attacker to steal cookie-based authentication credentials and to launch other attacks.
Community Server 2007 and 2008 are vulnerable; other versions may also be affected.
