Re: [OpenSER-Users] my small security breach REGISTER

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a security matter with my configuration (default one), it's possible to register using login/password and to set anything in the contact field. So if you have an account 106/password, it's possible to be 105 in the location database! How is it possible to deny that kind of matter..? Thanks Is it useful to use: method_filtering of the REGISTRAR module Or is it better to so something whith the values below and a compare function?? $ct - reference to body of contact header $ar - realm from Authorization or Proxy-Authorization header $au - username from Authorization or Proxy-Authorization header if ($ct != $au@$ar) { sl_send_reply("403", "User and login must be the same"); }; Best Regards, Marc LEURENT # U 82.127.0.79:1045 -> 88.191.45.91:5060 REGISTER sip:sd-7501.dedibox.fr;user=phone SIP/2.0.
