Flask Issue and http://127.0.0.1:5000 cannot open.

[ThePuteh]

Once followed the common instrucction, the requirements.txt should be followed by ./startup.sh provided by the git from malwaredllc/byob,

1. But the flask are the issue in which i use pip to manually install it and re-run the ../startup.ssh which avoid to run the web-page properly at http://127.0.0.1:5000.

2. Re-run again and using the other version of flask still no changes. FIrst place i thought its about ufw block the 5000 but its checked and no issue with firewall.

3. The issue printed like this :
   Navigate to http://127.0.0.1:5000 and set up your user to get started.

During handling of the above exception, another exception occurred:

Any idea ? I was thinking it may be of the flask issue.

1. The first running ./.startup show that no modules of flask.
   The issue found first is here, the flask:

Navigate to http://127.0.0.1:5000 and set up your user to get started.
Traceback (most recent call last):
File "/root/byob/web-gui/run.py", line 1, in
from buildyourownbotnet import create_app
File "/root/byob/web-gui/buildyourownbotnet/init.py", line 2, in
from flask import Flask
ModuleNotFoundError: No module named 'flask'
(So i decide to use pip install flask and pip install flask_login)

2. Next it appear as the first comment above which my browser cannot open the http://127.0.0.1:500 ..

I am using :
uname -r ubuntu 6.2.0-39-generic
Python 3.10.12
Docker version 24.0.5, build 24.0.5-0ubuntu1~22.04.1

I wonder some people said byob are long dead project. Encourage me and consider this as bug to fix and hoping that i can contribute with it to encourage byob.

same issue here

Testing with Deimos, i found that the server will automatically bind 127.0.0.1 as web app, and there's an issue for its payload, specific for Deimos, so by disabling specific NIC and re-run then it work properly. (Recommended to not enable multiple NIC).

And i wondering that the same issue with byob happen, let me check the NIC issue.
imo, running c2 web app should point the service as a server to your specific gateway that are used to make it properly.

Tallying both Deimos and BYOB issue. but i hope flask issue is not the issue after that.

has this been fixed yet?

has this been fixed yet?

Not yet ..

[tiiraluoto]

does an earlier version work?

[ThePuteh]

does an earlier version work?

The issue up above is for flask older version, once try with latest flask by manually pip the flask, and later remove it and use another older version, still no joy ..

The default in requirements.txt still give me no joy ..

reinstall requirements.txt or manually install every module that brings errors, also make sure you're going to the right URL, as OP said that he went to "127.0.0.1:500"
