CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
b2evolution 1.x
https://secunia.com/product/12768/

DESCRIPTION:
tarkus has discovered some vulnerabilities in b2evolution, which can
be exploited by malicious people to conduct cross-site scripting
attacks.

Input passed to the "app_name" parameter in _404_not_found.page.php,
_410_stats_gone.page.php and _referer_spam.page.php, "baseurl" in
_404_not_found.page.php and "ReqURI" in _referer_spam.page.php is not
properly sanitised before it is 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. All scripts are
located in the inc/VIEW/errors directory.

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities are confirmed in version 1.8.5. Other versions
may also be affected.

SOLUTION:
Fixed in the CVS repository.
