TITLE:
PHP Multiple Newsletters File Inclusion and Cross-Site Scripting

SECUNIA ADVISORY ID:
SA33065

VERIFY ADVISORY:
http://secunia.com/advisories/33065/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Exposure of system information, Exposure of
sensitive information

WHERE:
>From remote

SOFTWARE:
PHP Multiple Newsletters 2.x
http://secunia.com/advisories/product/20712/

DESCRIPTION:
Ahmadbady has discovered some vulnerabilities in PHP Multiple
Newsletters, which can be exploited by malicious people to conduct
cross-site scripting attacks and disclose sensitive information.

1) Input appended to the URL after [installation path]/index.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 the context of an affected site.

2) Input passed to the "lang" parameter in [installation
path]/index.php is not properly verified before being used to include
files. This can be exploited to include arbitrary files from local
resources via directory traversal attacks and URL-encoded NULL
bytes.

Successful exploitation of this vulnerability requires that
"magic_quotes_gpc" is disabled.

These vulnerabilities are confirmed in version 2.7. Other versions
may also be affected.

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