Lostmon has reported some vulnerabilities in BMForum Plus! and BMForum Datium!, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "page" and "filename" parameters in "topic.php", the "listby", "jinhua" and "page" parameters in "forums.php", the "forumid" parameter in "post.php" and the "forumid" parameter in "announcesys.php" isn't 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.

It is also possible to disclose the full path to certain scripts by accessing them directly and disclose some system information via certain files exposed inside the web root.

The vulnerabilities have been reported in version 2.6.1. The release candidates 3.0 RC1 through 3.0 RC3 is also affected. Other versions may also be affected.
