From 6000f4ad6d1e5ea69b3e0925217d08401a3d1774 Mon Sep 17 00:00:00 2001 From: Valentin Bartenev Date: Wed, 27 Feb 2013 17:38:54 +0000 Subject: SNI: reset to default server if requested host was not found. Not only this is consistent with a case without SNI, but this also prevents abusing configurations that assume that the $host variable is limited to one of the configured names for a server. An example of potentially unsafe configuration: server { listen 443 ssl default_server; ... } server { listen 443; server_name example.com; location / { proxy_pass http://$host; } } Note: it is possible to negotiate "example.com" by SNI, and to request arbitrary host name that does not exist in the configuration above. --- src/http/ngx_http_request.c | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'src/http/ngx_http_request.c') diff --git a/src/http/ngx_http_request.c b/src/http/ngx_http_request.c index 44c5009bd..bb4cacabd 100644 --- a/src/http/ngx_http_request.c +++ b/src/http/ngx_http_request.c @@ -1869,6 +1869,17 @@ ngx_http_set_virtual_server(ngx_http_request_t *r, ngx_str_t *host) return NGX_ERROR; } +#ifdef SSL_CTRL_SET_TLSEXT_HOSTNAME + + if (hc->ssl_servername) { + if (rc == NGX_DECLINED) { + cscf = hc->addr_conf->default_server; + rc = NGX_OK; + } + } + +#endif + if (rc == NGX_DECLINED) { return NGX_OK; } -- cgit v1.2.3
