Concrete Multiple XSS

While I was playing around with Concrete CMS, I wanted to know how this application shows us a hyperlink to the “Back” button. I found something interesting in the “download_file.php” file.


line 27

[code language=”php” highlight=”5″]
<form action="<?php echo View::url(‘/download_file’, ‘submit_password’, $fID) ?>" method="post">
<?php if(isset($force)) { ?>
<input type="hidden" value="<?php echo $force ?>" name="force" />
<?php } ?>
<input type="hidden" value="<?php echo $returnURL ?>" name="returnURL" />
<input type="hidden" value="<?php echo $rcID ?>" name="rcID"/>
<label for="password"><?php echo t(‘Password’)?>: <input type="password" name="password" /></label>
<br /><br />
<button type="submit"><?php echo t(‘Download’)?></button>

Let’s have a look at the “$returnURL” variable. (more…)

MyBB 1.6.12 POST XSS 0day

This is a weird bug I found in MyBB. I fuzzed the input of the search.php file. This was my input given.

alert (bar) () ; // ' " > < prompt \x41 %42 constructor onload

MyBB throws out a SQL error:

[code language=”sql”]
SELECT t.tid, t.firstpost
FROM mybb_threads t
WHERE 1=1 AND t.closed NOT LIKE ‘moved|%’
AND ( LOWER(t.subject) LIKE ‘%&lt;foo&gt; &lt;h1&gt; &lt;script&gt; alert (bar) () ; //%’ LOWER(t.subject)
LIKE ‘%&gt; &lt; prompt \x41 \%42 constructor onload%’)
