MongoDB的授权和权限 1. 在开启MongoDB 服务时不添加任何参数时,可以对数据库任意操作,而且可以远程访问数据库。如果启动的时候指定auth参数,可以对数据库进行用户验证。 www.2cto.com $ ./mongod --auth mongodb.log 开启 ./mongo MongoDB shell version
MongoDB的授权和权限
1. 在开启MongoDB 服务时不添加任何参数时,可以对数据库任意操作,而且可以远程访问数据库。如果启动的时候指定—auth参数,可以对数据库进行用户验证。 www.2cto.com
$ ./mongod --auth >> mongodb.log & 开启
./mongo
MongoDB shell version: 1.8.1
connecting to: test
>show dbs
admin (empty)
local (empty)
2. 添加用户
在刚安装完毕的时候MongoDB都默认有一个admin数据库,而admin.system.users中将会保存比在其它数据库中设置的用户权限更大的用户信息。
当admin.system.users中一个用户都没有时,即使mongod启动时添加了--auth参数,如果没有在admin数据库中添加用户,此时不进行任何认证还是可以做任何操作,直到在admin.system.users中添加了一个用户。
下面创建数据库tage,并给tage创建用户:
> use tage
switched to db tage
> db.addUser("tage","123")
{
"user" : "tage",
"readOnly" : false,
"pwd" : "1f66d5c4223029536080d41febe0ec33"
}
在admin库中创建root用户:
> use admin
switched to db admin
> db.addUser("root","123456")
{
"user" : "root",
"readOnly" : false,
"pwd" : "34e5772aa66b703a319641d42a47d696"
}
3. 验证用户:
> db.auth("root","123")
0 密码错误,返回0,验证失败
> db.auth("root","123456")
1 验证成功,返回1
下面试验用户权限设置:
$ ./mongo 登录时不加用户名与密码
MongoDB shell version: 1.8.1
connecting to: test
> use tage
switched to db tage
> db.system.users.find()
error: {
"$err" : "unauthorized db:tage lock type:-1 client:127.0.0.1",
"code" : 10057
}
4. 以上验证说明,登录时不指定用户名与密码,就会报错。下面指定用户与密码
$ ./mongo -uroot -p123456 指定用户与密码,但是不指定库名
MongoDB shell version: 1.8.1
connecting to: test
Wed Aug 3 21:30:42 uncaught exception: login failed
exception: login failed
mongodb登录时默认连接test库,如果登录时不指定库名,就会报错
5. 下面以tage库的用户名登录进行验证:
$ ./mongo tage -utage -p123
MongoDB shell version: 1.8.1
connecting to: tage
> db.system.users.find() 对所属自己的库进行操作,有权限
{ "_id" : ObjectId("4e394c696b50a56254359088"), "user" : "tage", "readOnly" : false, "pwd" : "1f66d5c4223029536080d41febe0ec33" }
> use admin
switched to db admin
> db.system.users.find() 对其他库操作,没有权限
error: {
"$err" : "unauthorized db:admin lock type:-1 client:127.0.0.1",
"code" : 10057
}
6. 下面以admin库下的root用户登录进行验证:
./mongo admin -uroot -p123456
MongoDB shell version: 1.8.1
connecting to: admin
> db.system.users.find()
{ "_id" : ObjectId("4e394caf6b50a56254359089"), "user" : "root", "readOnly" : false, "pwd" : "34e5772aa66b703a319641d42a47d696" }
> use tage
switched to db tage
> db.system.users.find() 对其他库进行操作,有权限
{ "_id" : ObjectId("4e394c696b50a56254359088"), "user" : "tage", "readOnly" : false, "pwd" : "1f66d5c4223029536080d41febe0ec33" }
7. mongodb的远程用户连接
语法结构:mongo –uusername –ppwd ServerIP:port/dbname
其中port默认为27017
$ ./mongo -uroot -p123456 192.168.2.150/admin
MongoDB shell version: 1.8.1
connecting to: 192.168.2.150/admin
> db.system.users.find()
{ "_id" : ObjectId("4e394caf6b50a56254359089"), "user" : "root", "readOnly" : false, "pwd" : "34e5772aa66b703a319641d42a47d696" }

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
