Re: [OpenSIPS-Users] sipmsg_validate not detecting wrong user agent

[Bogdan-Andrei Iancu]

Hi Sharad,

The sipmsg_validate() function does not perform any checks on the 
content of the User-Agent hdr - it only checks if the hdr has a 
non-empty body.


Best regards,

Hi guys,

We are using openSIPS for edge proxy and one of our client is sending 
wrong user-agent which is not compliant with RFC.

This is the username which is being passed -
Asterisk PBX 1.8.23.0-1_centos5.go RPM by dem...@goautodial.com 
\r\n


Where @ is not allowed in user-agent header. We are using this 
function in openSIPS to validate SIP headers but this function not 
seems to be working and not rejecting that INVITE.

if (!sipmsg_validate("shrftc")){
  send_reply("400","Bad request/body");
  exit;
}

Thank you
