Description:
Maksymilian Arciemowicz has reported some vulnerabilities in PostNuke, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks, and to bypass certain security restrictions.
1) It is possible to bypass the HTML tag filter implemented in "pnVarCleanFromInput()" and "pnAntiCracker()" via specially-crafted HTML tags.
Example:
<HTMLTAG? <
2) Input passed to the "htmltext" parameter in user.php and to the "language" parameter in the NS-Languages module isn't 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.
Example:
http://[host]/user.php?op=edituser&htmltext=[code]
http://[host]/admin.php?module=NS-Languages&op=missing&language=">[code]
http://[host]/admin.php?module=NS-Languages&op=translation&language=[code]
3) An access control error in admin.php can be exploited to access certain modules like NS-Languages and Banners without requiring admin privilege.
Example:
http://[host]/admin.php?module=NS-Languages
http://[host]/admin.php?module=Banners
4) Input passed to the "language" parameter in the NS-Languages module isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Example:
http://[host]/admin.php?module=NS-Languages&op=missing&language=[sql]
Successful exploitation requires that "magic_quotes_gpc" is disabled.
The vulnerabilities have been reported in version 0.761 and prior.
Solution:
Update to version 0.762.
