CVE-2006-2146


Description:
Aliaksandr Hartsuyeu has reported some vulnerabilities in HB-NS, which can be exploited by malicious people to conduct script insertion or SQL injection attacks.

1) Input passed to the "poster_name", "poster_email", "poster_homepage", and "message" parameters is not properly sanitised before being used. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site when malicious data is viewed.

2) Input passed to the "topic" and "id" parameters in index.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 requires that "magic_quotes_gpc" is disabled.

The vulnerabilities have been reported in version 1.1.6. Other versions may also be affected.

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

Provided and/or discovered by:
Aliaksandr Hartsuyeu
