Habari HB-Cumulus Plugin "tagcloud" Cross-Site Scripting Vulnerability


Description   MustLive has discovered a vulnerability in the HB-Cumulus plugin for Habari, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the "tagcloud" parameter to user/plugins/hb-cumulus/lib/tagcloud.swf (when "mode" is set to "tags") is not properly sanitised before being returned to the user.
