From b4d6b70d7f2e8207df02ab354da907475dcab8a5 Mon Sep 17 00:00:00 2001 From: Maxim Dounin Date: Thu, 20 Feb 2020 16:19:34 +0300 Subject: [PATCH] Removed "Transfer-Encoding: identity" support. The "identity" transfer coding has been removed in RFC 7230. It is believed that it is not used in real life, and at the same time it provides a potential attack vector. --- src/http/ngx_http_request.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/src/http/ngx_http_request.c b/src/http/ngx_http_request.c index 85c980378..9e64fd293 100644 --- a/src/http/ngx_http_request.c +++ b/src/http/ngx_http_request.c @@ -1952,10 +1952,7 @@ ngx_http_process_request_header(ngx_http_request_t *r) r->headers_in.content_length_n = -1; r->headers_in.chunked = 1; - } else if (r->headers_in.transfer_encoding->value.len != 8 - || ngx_strncasecmp(r->headers_in.transfer_encoding->value.data, - (u_char *) "identity", 8) != 0) - { + } else { ngx_log_error(NGX_LOG_INFO, r->connection->log, 0, "client sent unknown \"Transfer-Encoding\": \"%V\"", &r->headers_in.transfer_encoding->value);
