Redis Unauthorized Verification

Redis Unauthorized Verification Definition

Redis Unauthorized Authentication is the ability to access the Redis server without a password or authentication.

Verification steps

Verifying that Redis unauthorized access requires the following steps:

1. Get Redis server address and port : Get it from the server administrator or system log.

2. Connect using Telnet or Netcat : Use one of the following commands in the terminal:

   • Telnet: telnet [Redis 服务器地址] [端口]
   • Netcat: nc -vv [Redis 服务器地址] [端口]
3. Check if you can connect : If you can connect, the Redis prompt "redis>" will be displayed.
4. Execute the command : Enter the info command to obtain information about the Redis server.
5. Check Response : If a response is received, it means that the server is not authorized to access.

Example

Assume that the address of the Redis server is 192.168.1.100 and the port is 6379:

 <code># 使用Telnet 连接$ telnet 192.168.1.100 6379 Trying 192.168.1.100... Connected to 192.168.1.100. Escape character is '^]'. redis> # 执行info 命令redis> info # 服务器信息响应...</code>

This example shows that the Redis server is not authorized to access.
