The command line tool also independently sets --ftp-skip-pasv-ip by default. Ten test cases updated to adapt the modified --libcurl output. Bug: https://curl.se/docs/CVE-2020-8284.html CVE-2020-8284 Reported-by: Varnavas Papaioannou

.TH CURLOPT_FTP_SKIP_PASV_IP 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_FTP_SKIP_PASV_IP \- ignore the IP address in the PASV response
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_SKIP_PASV_IP, long skip);
|
|
.SH DESCRIPTION
|
|
Pass a long. If \fIskip\fP is set to 1, it instructs libcurl to not use the IP
|
|
address the server suggests in its 227-response to libcurl's PASV command when
|
|
libcurl connects the data connection. Instead libcurl will re-use the same IP
|
|
address it already uses for the control connection. But it will use the port
|
|
number from the 227-response.
|
|
|
|
This option thus allows libcurl to work around broken server installations
|
|
that due to NATs, firewalls or incompetence report the wrong IP address
|
|
back. Setting the option also reduces the risk for various sorts of client
|
|
abuse by malicious servers.
|
|
|
|
This option has no effect if PORT, EPRT or EPSV is used instead of PASV.
|
|
.SH DEFAULT
|
|
1 since 7.74.0, was 0 before then.
