4) Description of Vulnerability

Secunia Research has discovered multiple vulnerabilities in KubeBlog, 
which can be exploited by malicious people to conduct cross-site 
scripting attacks.

1) Input passed via the "username" parameter to login.php, the 
"wysiwyg" parameter to adm/editor_flickr.php and 
adm/editor_zooomr.php, the "message" parameter to adm/index.php, and 
the "name", "email", and "website" parameters to post.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.

2) Input appended to the URL after adm/cat_view.php, 
adm/comment_view.php, adm/content_view.php, adm/post_view.php, and
adm/users_view.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.

5) Solution 

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