DESCRIPTION:
icetek has discovered some vulnerabilities in XWiki Watch, which can
be exploited by malicious people to conduct cross-site scripting and
script insertion attacks.

1) Input passed via the "rev" parameter to e.g.
xwiki/bin/viewrev/Main/WebHome or xwiki/bin/view/Blog 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.

2) Input passed via the "register_first_name" and
"register_last_name" parameters to xwiki/bin/register/XWiki/Register
is not properly sanitised before being displayed to the user. This
can be exploited to insert arbitrary HTML and script code, which will
be executed in a user's browser session in context of an affected site
when the malicious data is being viewed.

The vulnerabilities are confirmed in version 1.0. Other versions may
also be affected.

SOLUTION:
Filter malicious characters or character sequences via a proxy.
