So I tested out some injection on Model::save() and found this out ;( |

I was fooling with prepared statements using $this->query() last night (thanks for the patch btw markstory; it really kicks ass) but was curious about switching over to standard $this->save() and $this->updateAll(). I found it interesting that you cannot use prepared statements with updateAll() though which makes it very difficult to securely use; so I looked at what Model::save() does, but it just passes the stuff to update(). |

because the '--' comments everything else out afterwords (e.g., the WHERE id = 5) |

Here is the string I tried: $this->save(array('User'=>array('username'=>'test --')), false) which resulted in everyone's username being changed to 'test' |

updateAll is supposed to. |
| # |
Aug 21st 2009, 16:39 |
kiger |
well updateAll() clearly does, but doing an update through save() does too |
| # |
Aug 21st 2009, 16:39 |

So I do $this->User->id = $userId |
| # |
Aug 21st 2009, 16:39 |
markstory |
so you're saying all update commands allow sql injection? |

I allow users to edit their account on my box |

ok |

[18:04] <kiger> $success = (bool)$db->update($this, $fields, $values); |
| # |

[18:04] <kiger> check line 1238 in the latest svn of model.php |

and should escape fields. |

Model::save() doesn't use updateAll |
| # |
Aug 21st 2009, 16:35 |
kiger |
But I never realized that Model::save() does not escape stuff either when you set Model->id because it will also use update. |
| # |
Aug 21st 2009, 16:34 |
kiger |
Basically, I didn't know that updateAll() doesn't escape stuff; the docs say it doesn't so no problem |
| # |
Aug 21st 2009, 16:32 |

Should I mention it in here or does someone want me to explain in a pm? |

I think, and of course I'm probably wrong, I found a pretty big hole in cake regarding security that maybe many bakers don't know about? |

whats bad about prefering stuff like lowercase tagnames and attributes, tags closing with /> etc |

a lot of people use bad tools. because they like them or are used to them. thats fine. tool makers should make good tools though |
