DESCRIPTION:
Multiple vulnerabilities have been reported in Contentpapst, which
can be exploited by malicious users to conduct script insertion
attacks and by malicious people to conduct cross-site scripting
attacks.

1) Input passed to the "form[search]" parameter in admin.php (when
"file" is set to "news") 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 "form[title]", "form[description]", and
"form[permalink]" parameters to admin.php when creating a category 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.

3) Input passed via the "form[name]", "form[meta_description]", and
"form[permalink]" parameters to admin.php when creating an article 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.

4) Input passed via the "form[newstitle]", "form[permalink]",
"form[link1]", "form[link2]", and "form[link3]" parameters to
admin.php when creating a news post 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.

Successful exploitation of vulnerabilities #2-#4 requires "Redakteur"
privileges.

5) Input passed via the "form[title]", "form[desc]", and "form[url]"
parameters to admin.php when creating a link 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.

Successful exploitation of vulnerability #5 requires "Chefredakteur"
privileges.

The vulnerabilities are reported in version 2011.2. Other versions
may also be affected.

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