You mean affected?  `Effected` is not a word.

I pasted the following example XSS code into both form fields, and saw no evidence of XSS vulnerabilities:

<DIV STYLE="background-image: url(javascript:alert('XSS'))">

<DIV STYLE="background-image:\0075\0072\006C\0028'\006a\0061\0076\0061\0073\0063\0072\0069\0070\0074\003a\0061\006c\0065\0072\0074\0028.1027\0058.1053\0053\0027\0029'\0029">

<DIV STYLE="background-image: url(&#1;javascript:alert('XSS'))">

<DIV STYLE="width: expression(alert('XSS'));">

Did you have an example of a <div> tag that works?

> leaveCommentReply.php

Since the same form input cleansing code is in place for all forms and incoming GPC data site-wide, I did not test this form page.

Full path disclosure only occurs when the error reporting level $GLOBALS[ 'SITE_DEBUG' ] is set on.  In production mode, $GLOBALS[ 'SITE_DEBUG' ] = 0, so full paths are never shown.  I don't consider this an exploit as the script users are told the proper setting for production deployment is 0.  Neverthless I have changed the default setting from 1 to 0 in the distribution copy of config.php-dist.

Even though I am unable to find any example XSS code that works as you described, I will go ahead and remove the <div> tag from the allowed tag list in the config.php-dist file.

Alot of people use this script, thanks for no early/private disclosure whatsoever.
