What if your photos get deleted without your knowledge?

Obviously, that’s very disgusting, isn’t it? Yup this post is regarding a vulnerability found by me which allows a malicious user to delete any photo album on Facebook. Any photo album owned by a user or a page or a group could be deleted.

Graph API is the primary way for developers to read and write the users data. All the Facebook apps of now are using Graph API. In general Graph API requires an access token to read or write user data. Read more about Graph API here.

According to Facebook developers documentation, photo albums cannot be deleted using the album node in Graph API.

I tried to delete one of my photo albums using graph explorer access token.

Request :-

DELETE /518171421550249 HTTP/1.1

Host :  graph.facebook.com 

Content-Length: 245

access_token=CAACEd…..MUZD

 

Response :-

{“error”:{“message”:”(#200) Application does not have the capability to make this API call.”,”type”:”OAuthException”,”code”:200}}

Why? Because this application doesn’t have the capability to delete photo album. But we need to note the error message. It tells us that some other application does have the capability to make this API call 😛

I decided to try it on Facebook for mobile access token because it is a top-level access token which has some extra permissions. Facebook mobile apps use the same Graph API. so took an album id & Facebook for Android access token of mine and tried it.

Request :-

DELETE /518171421550249 HTTP/1.1

Host :  graph.facebook.com 

Content-Length: 245

access_token=<Facebook_for_Android_Access_Token>

 

Response:-

true

Album(518171421550249) got deleted 😀 so whats the next step? Took victim’s album id and tried to delete it. I was very curious to see the result.

Request :-

DELETE /518171421550249 HTTP/1.1

Host :  graph.facebook.com 

Content-Length: 245

access_token=<Facebook_for_Android_Access_Token>

 

Response:-

true

OMG 😀 the album got deleted! So what? I got access to delete all of your Facebook photos (photos which are public or the photos I could see) 😛 lol 😀

  5. Virtually , you can use this method to delete any photo albums that belongs to a user who have registered to your facebook app , not any facebook user.

  6. Nice find. Keep inspiring people. 🙂 I have one silly question, hope i will get the answer. I cannot understand how is it showing "facebook for android" with app id, in APP ID section on your access token page.
    I actually created one facebook page long back and it is showing that page app id in the access token page.
