CWH Underground has discovered some vulnerabilities in 427BB, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "post" parameter in showpost.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed via the URL to register.php, reminder.php, and search.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.

3) Input passed to the "uname", "email", and "email2" parameters in register.php, to the "email" parameter in reminder.php, and to the "keywords" parameter in search.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 are confirmed in version 2.3.1. Other versions may also be affected.
