Description:
__GiReX__ has reported some vulnerabilities in miniBB, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "lang" parameter in index.php (if "action" is set to "registernew") 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.

2) Input passed to the "xtr" parameter in index.php (if "action" is set to "userinfo") 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 "register_globals" is enabled.

Note: A full path disclosure issue in index.php is also reported.

The vulnerabilities are reported in version 2.2. Other versions may also be affected.

Solution:
Update to version 2.2a.

Provided and/or discovered by:
