I've just tested the scenario below on my 8.0.2 Sametime on windows, and indeed, it is vulnerable. Beware if you have outward facing Sametime servers:

Vulnerable Domino Sametime 8.0.1

Domino Sametime 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.

Domino Sametime 8.0.1 is known to be vulnerable. Other versions may also be vulnerable.

To exploit this issue, an attacker must entice an unsuspecting victim into following a malicious URI, such as the following:

http://host/stconf.nsf/WebMessage?OpenView&messageString="><script>alert
("XSS!")=</script>#

http://host/stconf.nsf/");} alert("XSS!"); function a(){ var a=unescape("

It is currently unknown whether vendor updates are available for this issue.
