MongoDB的相关安全问题


记得去年的时候因为工作需要调研过一段时间的MongoDB,不过后来因为别的原因就没有深入,这次又碰到了,所以,顺便从网上找了一些教程,了解它的一些相关安全问题,记录如下:

工具:

扫描 https://github.com/tcstool/NoSQLMap
GUI连接 MongoVUE

文档:

MongoDB官方文档
MongoDB安全配置

相关案例:

http://www.wooyun.org/searchbug.php #搜索“MongoDB”

扫描脚本:
#!/usr/bin/env python
# coding=utf-8
import pymongo
def mongoScan(ip, port):
try:
    conn = pymongo.MongoClient(ip, port, connectTimeoutMS=4000, socketTimeoutMS=4000)
    try:
        dbList = conn.database_names()
        dbVer = conn.server_info()['version']
        conn.disconnect()
        print "Successful access with no credentials!"
        return [0, dbVer]
    except:
        if str(sys.exc_info()).find('need to login') != -1:
            conn.disconnect()
            print "Login required!"
            return [1, None]
        else:
            conn.disconnect()
            print "Access check failure."
            return [2, None]

except:
    print "Couldn't connect to Mongo server."
    return [3, None]

runProgram(program[, args...]) same as run(), above
sleep(m) sleep m milliseconds
getMemInfo() diagnostic
> help connect

Normally one specifies the server on the mongo shell command line. Run mongo --help to see those options.
Additional connections may be opened:

var x = new Mongo('host[:port]');
var mydb = x.getDB('mydb');
or
var mydb = connect('host[:port]/mydb');

Note: the REPL prompt only auto-reports getLastError() for the shell command line connection.

> help keys
Tab completion and command history is available at the command prompt.

Some emacs keystrokes are available too:
Ctrl-A start of line
Ctrl-E end of line
Ctrl-K del to end of line

Multi-line commands
You can enter a multi line javascript expression. If parens, braces, etc. are not closed, you will see a new line
beginning with '...' characters. Type the rest of your expression. Press Ctrl-C to abort the data entry if you
get stuck.

> help misc
b = new BinData(subtype,base64str) create a BSON BinData value
b.subtype() the BinData subtype (0..255)
b.length() length of the BinData data in bytes
b.hex() the data as a hex encoded string
b.base64() the data as a base 64 encoded string
b.toString()

b = HexData(subtype,hexstr) create a BSON BinData value from a hex string
b = UUID(hexstr) create a BSON BinData value of UUID subtype
b = MD5(hexstr) create a BSON BinData value of MD5 subtype

o = new ObjectId() create a new ObjectId
o.getTimestamp() return timestamp derived from first 32 bits of the OID
o.isObjectId()
o.toString()
o.equals(otherid)

一些tips小结:

① 在Web页面查看MongoDB的相关信息

http://x.x.x.x:27017
You are trying to access MongoDB on the native driver port. For http diagnostic access, add 1000 to the port number
http://x.x.x.x:28017

② MongoDB远程连接配置

1.添加管理员账号

> use admin
switched to db admin
> db.addUser('tank','test');

2.配置mongodb.conf

#bind_ip = 127.0.0.1 //注释此行
auth = true //将此行前的注释去掉

3.重启mongodb

4.防火墙开放27017端口

iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 27017 -j ACCEPT

5.远程连接测试

$ mongo x.x.x.x:27017/db_name -u admin -p
……输入密码……
