DESCRIPTION:
High-Tech Bridge SA has discovered multiple vulnerabilities in HESK,
which can be exploited by malicious people to conduct cross-site
scripting attacks.

1) Input passed to the "hesk_settings[tmp_title]" and
"hesklang[ENCODING]" parameters in /inc/header.inc.php 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.

Successful exploitation of this vulnerability requires that
"register_globals" is enabled.

2) Input passed via the URL to language/en/test.php 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 vulnerabilities are confirmed in version 2.2. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
High-Tech Bridge SA.
