TITLE:
PostNuke Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA11406

VERIFY ADVISORY:
http://secunia.com/advisories/11406/

CRITICAL:
Moderately critical

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

WHERE:
From local network

SOFTWARE:
PostNuke 0.x

DESCRIPTION:
Janek Vind has reported some vulnerabilities in PostNuke. These can
be exploited by malicious people to conduct Cross Site Scripting and
SQL injection attacks.

1) The problem is that input passed to the "deleteNotice" parameter
in "admin.php" isn't properly verified. This can be exploited by
supplying invalid values / characters to reveal the installation
path.

2) Input passed to the "order" parameter in the NS-Polls module isn't
properly verified before it is returned to the user. This can be
exploited to execute arbitrary HTML or script code in a user's
browser session in context of an affected site by tricking the user
into visiting a malicious website or follow a specially crafted
link.

3) Input passed to the "thold" parameter in NS-Polls module isn't
properly verified before it is used in an SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities have been reported in version 0.7.2.6.

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

PROVIDED AND/OR DISCOVERED BY:
Janek Vind "waraxe"
