TITLE:
MWNewsletter Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA19568

VERIFY ADVISORY:
http://secunia.com/advisories/19568/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
From remote

SOFTWARE:
MWNewsletter 1.x
http://secunia.com/product/9228/

DESCRIPTION:
Some vulnerabilities have been discovered in MWNewsletter, which can
be exploited by malicious people to conduct script insertion attacks
and SQL injection attacks.

1) Input passed to the "user_name" parameter in subscribe.php is not
properly sanitised before being saved. This can be exploited to
execute arbitrary HTML and script code in an administrator's browser
session in context of an affected site when malicious data is
viewed.

2) Input passed to the "user_name" parameter in unsubscribe.php is
not properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed to the "user_email" parameter in unsubscribe.php and
to the "user_name" and "user_email" parameters in subscribe.php is
not properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerabilities have been confirmed in version 1.0.0b. Other
versions may also be affected.

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