The version of Novell GroupWise installed on the remote Windows host is earlier than 8.0.2 HP3. It is, therefore, reportedly affected by a cross-site scripting vulnerability because the application fails to sanitize user-supplied input to the ‘Directory.Item.name’ and ‘Directory.Item.displayName’ parameters.
A remote attacker may be able to exploit this vulnerability to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site.
