TITLE:
PHP-Nuke vWar Module SQL Injection and Cross-Site Scripting

SECUNIA ADVISORY ID:
SA24887

VERIFY ADVISORY:
http://secunia.com/advisories/24887/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, Exposure of sensitive
information

WHERE:
>From remote

SOFTWARE:
vWar 1.x (module for PHP-Nuke)
http://secunia.com/product/13959/

DESCRIPTION:
Janek Vind has discovered some vulnerabilities in the vWar module for
PHP-Nuke, which can be exploited by malicious people to conduct SQL
injection attacks and cross-site scripting attacks.

1) Input passed to the "n" parameter in extra/online.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 allows e.g. retrieving administrator
usernames, password hashes, and e-mail addresses, but requires
knowledge of vWar's database table prefix.

2) Input passed to the "title" parameter in extra/today.php (when
"whattoshow" is set to "3") is not properly sanitised before being
returned to a user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

3) Input passed to the "memberlist" parameter in extra/login.php is
not properly sanitised before being returned to a user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

Successful exploitation of this vulnerability requires that the
target user is not logged in.

The vulnerabilities are confirmed in version 1.5 R15. Other versions
may also be affected.

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