DESCRIPTION:
Sony has discovered two vulnerabilities in XWiki Enterprise, which
can be exploited by malicious users to conduct script insertion
attacks.

Input passed via the "XWiki.XWikiComments_comment" POST parameter to
e.g. xwiki/bin/commentadd/Main/WebHome when posting a comment and
"XWiki.XWikiUsers_0_company" POST parameter when editing a user's
profile is not properly sanitised before being used. 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 3.4. Other versions may
also be affected.

SOLUTION:
Filter malicious characters and character sequences using a proxy.
