DESCRIPTION:
Gjoko Krstic has discovered a vulnerability in Kentico CMS, which can
be exploited by malicious people to conduct cross-site scripting
attacks.

Input passed via the "userContextMenu_parameter" POST parameter to
examples/webparts/membership/users-viewer.aspx is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

The vulnerability is confirmed in version 5.5R2. Other versions may
also be affected.

SOLUTION:
Install hotfix 5.5R2.24
