Status: RESOLVED DUPLICATE of bug 723753

(Toolkit :: Blocklist Policy Requests, defect)

Description

[MarkH]

Attachment: 20120206 youtube2.zip

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_2) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.77 Safari/535.7

Steps to reproduce:

Installed the add-on from vayaina[.]in/video/budado/youtube.xpi


Actual results:

Add-on loads JS to inject http://budado.info/s.js, which injects
http://whos.amung.us/swidget/budado321.gif as an <img> tag and
http://budado.info/e/e.js as a <script> tag

E.js injects an <iframe> pointing to "http://famoso123.info/video/"+video+"/"+servidor+".html";, where video and servidor are provided at runtime.  The iframe is set to cover the webpage the victim is trying to navigate to.



Expected results:

It shouldn't inject an iframe into the user's tab, covering the intended page.

This is the same ID as bug 723753. Can you confirm that you can still install this add-on without any warnings?

I installed this one prior to filing the bug, no warnings or blocks popped up.

I just tried in several versions of Firefox and the block worked correctly. If you can consistently reproduce in a new profile, please let me know via email and we'll figure it out.
