Description:
DarkFig has discovered some vulnerabilities in NPDS, which can be exploited by malicious people to conduct cross-site scripting attacks and to disclose potentially sensitive information.
1) Input passed to the "ModPath" parameter in "/modules/cluster-paradise/cluster-E.php" is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.
Example:
http://[host]/modules/cluster-paradise/cluster-E.php?ModPath=[file]%00&key=a
Successful exploitation may require that the script is used on the Windows platform, and requires that "register_globals" is enabled and "magic_quotes_gpc" is disabled.
2) Input passed to the "nuke_url" parameter in /meta/meta.php, to the "forum" parameter in viewforum.php, to the "post_id", "forum", "topic", and "arbre" parameters in editpost.php, and to the "uname" and "email" parameters in user.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.
The vulnerabilities have been confirmed in version 5.10. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised.
