Description:
papipsycho has reported some vulnerabilities in Nuked-Klan, which can be exploited by malicious people to conduct script insertion and SQL injection attacks.

1) Certain input passed in the "Search", "Guestbook", "Forum", and "Textbox" modules isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed.

2) Input passed to the "forum_id", "thread_id", "link_id", "artid", and "dl_id" parameters isn't 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.

The vulnerabilities have been reported in version 1.7. Prior versions may also be affected.

Solution:
Apply patch.

NOTE:
The patch does not properly fix the SQL injection vulnerabilities.

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