Friendster XSS Through FBML

Posted by: Joy  :  Category: Linker, Vulnerability

Friendster FBML Hole Status : Filtered (September, 2010)
Released : August, 2010
Author : no_one
Greetings : Angell de Ville & The Friendster Team

MyFeeling Widget Linker

The last shoutout linker has been filtered already about a month after being released. Now i’m trying to share again another persistent xss on friendster that can be used to add layouts to our profile. Here, we’re gonna use the old FBML platform on friendster applications. as you might already know, actually this platform was already removed from their developer page about a year ago, but some of the old ones are still intact.

OK, let’s just go straight to the steps. Follow these instructions carefully :

1. Login to your friendster
2. Use this to generate the XSS code to bypass the filter

    :arrow: MyFeeling Linker Generator

3. Choose the script injection type you want to use
4. Put your JS and or CSS layout and or website URL on the box, then click generate
5. Copy the generated code
6. Add this application to your profile. dont forget to uncheck the invite friends checkbox
7. Replace the words “happy,sad, enter here” with the code from the generator
8. Press enter or click update profile at the bottom part of the widget
9. Check your profile, enjoy your layout.

As usual, remember, this is merely a temporary method to insert linker till they find out what we’re doing with their widget. Lolz, it feels like i’m the only one who is still playing with the friendster team :D

Happy tweaking ;)

    Dear Joy,
    Thank you so much for finding the new FS XSS, unfortunately only few Indonesian people still remain active in editing their profile, i’m the one of them, so I’m still waiting for your info, and finally, THANK YOU so much. I think you should post on Bli Oka’s forum, Thank you :)
