Hi there,
I have setup a test account and managed to steal my own cookie. I guess this was the easy part. Here's the output of my cookie stealer:
Cookie: phpbb2mysql_t=a:1:{i:110;i:1145043838;}; phpbb2mysql_data=a:2:{s:11:\"autologinid\";s:33:\"205340551044400583937258.37903461\";s:6:\"userid\";i:193;}; phpbb2mysql_sid=dd583d8eb8a767dcaf15efc2f751a272

I'm really having a hard time decyphering this and reading a hash from it. I can see the session id, but i dont think this would help me much since you always need to relog when u enter admin cp.
Any gurus out there? |

I think this is supposed to by the hash, but why is it a floating point number?
There is a way to get around relogging in admin CP you know with just the SID. Try this, for example
http://forum/phpbb/admin/usercp.php?sid=<your sid>&<enter an arguement for usercp here to execute>
Does this make sense? Correct me if I'm wrong and ask me if its unclear. |

it's not a hash, this is user identifier in phpbb forum version 2.0.18/19....
so it cann't be decoded. the real hash is stored in data base and didn't transmitted in cookies |
