[Kamailio-Users] kamailio 1.4 INVITE authentication bypass
by Asim Riaz 07 Sep '09

07 Sep '09

Hi List, I am using kamailio 1.4 and authenticating INVITE if the source ip address is not in trusted table but one of the IP which is not in the trusted table was able to bypass INVITE authentication, . I don’t have SIP traces saved from the called but when that was happening I could see that the INVITE didn’t have auth credentials but caller was able to bypass authentication and was sending calls to my upstream gateway. Caller’s IP is definitely not in the trusted table, I am just wondering is it something wrong in my script or similar issue has reported before ; Thanks in Advance Asim route[2] { xlog("L_INFO", "[ROUTE-2] Received initial INVITE from $si\n"); setflag(2); setflag(3); if(is_from_local()) { if(!allow_trusted()) { xlog("L_INFO", "[ROUTE-2 !] Issuing proxy challenge\n"); if(!proxy_authorize("", "subscriber")) { proxy_challenge("", "1"); exit; } else if(!check_from()) { xlog("L_INFO", "[ROUTE-2 !] From URI denied\n"); sl_send_reply("403", "Forbidden"); exit; } } else { xlog("L_INFO", "[ROUTE-2 !] From URI domain not local - denied\n"); sl_send_reply("403", "Forbidden"); exit; } } consume_credentials(); xlog("L_INFO", "[ROUTE-2 ->] Authentication credentials valid\n"); if(nat_uac_test("1")) { xlog("L_INFO", "[ROUTE-2 ->] RFC1918 contact found - fixing up\n"); fix_nated_contact(); force_rport(); setbflag(7); } if(nat_uac_test("8") && search("Content-Type: application/sdp")) { xlog("L_INFO", "[ROUTE-2 ->] RFC1918 SDP endpoint found - fixing up\n"); fix_nated_sdp("10"); } # Apply outbound translations and figure out where to route the call. route(4); # this route the calls to upstream gateway. } These messages i was getting in syslog [ROUTE-2] Received initial INVITE from xxx.xxx.xxx.xxx(Caller_IP) ERROR:auth:consume_credentials: no authorized credentials found (error in scripts) [ROUTE-2 ->] Authentication credentials valid [ROUTE-4] Applying outbound translations to: 0022334455 [ROUTE-4 ->] Translated RURI user part to: 22334455 [ROUTE-4 ->] Gateway election: my_upstream_gateway [ROUTE-5] Accounting translation: sip:0022334455@my_upstream_gateway [ROUTE-2 ->] Relaying

Hi Rajesh, please always CC to the list. As hinted in some other mail, perhaps the module use not the correct DB URL?

Hello all, I have done some modification in my ser.cfg. And when I decided to restart, it failed.

Can someone help me to understand why it failed ?

[Kamailio-Users] t_realy in failure_route?
by Ricardo Martinez 03 Sep '09

03 Sep '09

Hello I have a question. I hope that someone could clarify this to me. I have the next situation. I'm using a t_on_failure route along with the LCR module. So I have something like this : failure_route[1] { if (t_was_cancelled()) { xlog("L_INFO", "[$ci] $rm:$ru t_was_cancelled in failure_route\n"); exit; } if ( t_check_status("486") ) { xlog("L_INFO","[$ci] 486 Received\n"); } if (t_check_status("603")) { xlog("L_INFO","[$ci] 603 Received\n"); if (!next_gw()) { t_reply("503", "Service not available, no more gateways"); xlog("L_INFO", "[$ci] No hay mas gateways para $rm:$ou\n"); exit; } else { xlog("L_INFO", "[$ci] $rm cambiando $ou por $ru en failure_route"); } t_on_failure("1"); } t_relay(); } Maybe I'm misunderstanding how the failure_route works but with this configuration I was expecting that If I have a 603 from the callee I will do the "next_gateway" configuration. And If I have a 486 I will put a line in the log and then continue with the t_relay. So.. the 486 will be passed to the caller, but with the final answer from the caller ( ACK ) to the 486.. and I'm getting this error... Sep 2 16:43:41 ERROR:tm:t_forward_nonack: no branch for forwarding Sep 2 16:43:41 ERROR:tm:w_t_relay: t_forward_nonack failed So it seems that tries to forward the ACK with t_relay? Caller Proxy Callee ------> INVITE -----> INVITE <------ 486 -------> ACK <------ 486 -----> (error?) ACK But... When I modified the next lines in the failure_route if ( t_check_status("486") ) { xlog("L_INFO","[$ci] 486 Received\n"); exit; } And add the "exit" parameter, i don't have the above error and the "486" is passed back to the caller as "expected". Can someone explain me this? Thanks in advance.. Regards Ricardo Martinez.-
