Hey folks online ! Today i wanna express my personal researching of Badoo that i’m able to takeover anyone membership just by offering him/her a poisionous hyperlink

Badoo is a dating-focused social networking provider, established in 2006[4]and head office in Soho, London. This site functions in 180 countries and it is most widely used in Latin The usa, Spain, Italy and France.

To achieve higher characteristics, a user pays a fee or allow Badoo to e-mail all his/her friends.

Lets beginning

Firstly i want to thank my good friend Rudra which usually inspire me personally the guy given me personally an easy link and I also got away a merchant account takeover from it

The insect was really simple, it truly does work on a CSRF & A token missconfiguration. And simply legitimate for

Whenever we import photos from Facebook or Instagram they do not have any anti-CSRF token, the Twitter token which generated via Badoo was legitimate for everyuser. Now i can offer a link to a person of my personal fb levels to import pictures, if consumer will push on ok after that photograph are going to be brought in to their membership.

But how I acquired an takeover right here ?

The one thing i noticed that the web link produced can replace the user FB connected levels with attacker’s FB accounts while the best benefit was actually user simply need to go to website link no cancel or ok pressing requisite.

Now an assailant can login via FB and completely takeover the accounts and that can access all his speak, exclusive images and anything

The insect is patched within 2 times of intial document. Benefit ($850) ended up being quite much less from my personal hope .

Tips to replicate ended up being :-

1 -Create two Badoo accounts attacker & target and hyperlink 2 diff fb levels in each

2- Login as ‘attacker’ and go to transfer pictures via fb and copy the hyperlink from URL bar

3- today login as ‘victim’ in diffrent internet browser and opened the link and click cancel.

4- FB membership of ‘victim’ was replaced with FB accounts of ‘attacker’ (taken out of ‘attacker’ one)

5-Login via attacker’s FB account and you will certainly be logged in as ‘victim’ profile

Extra description

Suppose a user bring an account of assailant ‘A’ with FB linked which ‘FB-of-A’ and a prey membership ‘B’ with fb linked which can be ‘FB-of-B’ today attacker generate a web link to transfer photos from his fb and provide they to victim ‘B’ the guy starts it and newspapers cancel but this posses changed their FB profile ‘FB-of-B’ to attacker’s FB profile ‘FB-of-A’, and then attacker can login together with fb accounts in victim’s badoo fund.
