TITLE:
Falcon Series One Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA28047

VERIFY ADVISORY:
http://secunia.com/advisories/28047/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, System access

WHERE:
>From remote

SOFTWARE:
Falcon Series One 1.x
http://secunia.com/product/16878/

DESCRIPTION:
MhZ91 has reported some vulnerabilities in Falcon Series One, which
can be exploited by malicious people to conduct script insertion and
cross-site request forgery attacks and to compromise a vulnerable
system.

1) Input passed to the "dir[classes]" parameter in sitemap.xml.php is
not properly verified before being used to include files. This can be
exploited to include arbitrary files from local and external
resources.

Successful exploitation requires that "register_globals" is enabled.

2) Input passed to the "gb_mail", "gb_name", and "gb_text" parameters
in index.php (when "guestbook" is set to "v" 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 guestbook entry is
viewed.

3) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
request. This can be exploited to e.g. change the administrator's
password when a logged-in administrator is enticed to browse a
malicious web page.

The vulnerabilities are reported in version 1.4.3. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified and
sanitised. Do not browse untrusted web sites while being logged on to
the application.
