TITLE:
Membrepass Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA21715

VERIFY ADVISORY:
http://secunia.com/advisories/21715/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
Membrepass 1.x
http://secunia.com/product/11808/

DESCRIPTION:
DarkFig has discovered some vulnerabilities in Membrepass, which can
be exploited by malicious people to conduct cross-site scripting and
SQL injection attacks, and to compromise a vulnerable system.

1) Input passed to the "recherche" form field in parameter in
recherchemembre.php and to the "email" parameter in 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.

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

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

3) Input passed to multiple parameters in include/change.php is not
properly sanitised before being stored in a PHP script. This can be
exploited to inject and execute arbitrary PHP code.

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

The vulnerabilities have been confirmed in version 1.5. Other
versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
