TITLE:
iziContents Multiple File Inclusion Vulnerabilities

SECUNIA ADVISORY ID:
SA26931

VERIFY ADVISORY:
http://secunia.com/advisories/26931/

CRITICAL:
Highly critical

IMPACT:
Exposure of sensitive information, System access

WHERE:
From remote

SOFTWARE:
iziContents 1.x
http://secunia.com/product/15803/

DESCRIPTION:
irk4 has discovered some vulnerabilities in iziContents, which can be
exploited by malicious people to disclose sensitive information or to
compromise a vulnerable system.

1) Input passed to the "gsLanguage" parameter in
modules/search/search.php, modules/poll/inlinepoll.php,
modules/poll/showpoll.php, modules/links/showlinks.php, and
modules/links/submit_links.php (when "language_home" is set to an
empty string and "rootdp" is set to an arbitrary value) is not
properly verified before being used to include files. This can be
exploited to include arbitrary file from local and external
resources.

Successful exploitation requires that "register_globals" is enabled.

2) Input passed to the "admin_home" parameter in
modules/poll/poll_summary.php (when "rootdp" is set to an arbitrary
value) and to the "rootdp" parameter in include/db.php is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local resources.

Successful exploitation requires that "register_globals" is enabled
and "magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 1RC6. Other versions may
also be affected.

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