Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
Basic Usage
This module is a scanner module, and is capable of testing against multiple hosts.
msf > use auxiliary/scanner/redis/redis_login
msf auxiliary(redis_login) > show options
... show and set options ...
msf auxiliary(redis_login) > set RHOSTS ip-range
msf auxiliary(redis_login) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(redis_login) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(redis_login) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(redis_login) > set RHOSTS file:/tmp/ip_list.txt
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Vulnerable Application
Redis is an in-memory data structure project implementing a distributed, in-memory key-value database with optional durability. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indexes.
This module is login utility to find the password of the Redis server by bruteforcing the login portal. Note that Redis does not require a username to log in; login is done purely via supplying a valid password.
A complete installation guide for Redis can be found here
Verification Steps
- Do:
use auxiliary/scanner/redis/redis_login - Do:
set RHOSTS [ips] - Do:
set PASS_FILE /home/kali/passwords.txt - Do:
run
Options
PASS_FILE
The file containing a list of passwords to try logging in with.
