source precheck.sh errors

[kaster-san]

when i reached source precheck.sh i got these errors :

: command not found
E: Invalid operation update
: command not found
-bash: precheck.sh: line 14: syntax error near unexpected token `$'do\r''
'bash: precheck.sh: line 14: `for command in "${commands[@]}"; do

here is the content of precheck.sh

pip install -qr requirements.txt

echo "setup finished!"

can anyone point the reason ?

update : here is the fix :

 sudo apt install dos2unix
 dos2unix precheck.sh

@kaster-san This must be some issue due to editors or when you were transferring the file.
All files are prepared in and designed for linux environments so should be no need to convert to unix bytes.

[sreegopcs]

python cake_fuzzer.py instrument check
[-] Error detected by app_info: {'type': 'error', 'message': '() '}

how to resolve this error......i had made the setup as mentioned in the readme file

[dawid-czarnecki]

Can you describe your setup?

[sreegopcs]

Actually i had used ubuntu for the setup as host and used vmware on the top to launch misp ....and used the step specified in the readme.....intially i faced many errors....i resolved it...but now i am stuck with this error

[dawid-czarnecki]

If you use python3.6 it might not work because it doesn't have all the modules required (although it would be a different error than the one you see). Try python 3.8 or newer. Check:

• if your config points correctly to webroot of MISP (by default: /var/www/MISP/app/webroot/)
• if you are inside of the virutal environment when you run the command

I've just setup similar environment using MISP VMWare images, updated it, setup cake_fuzzer with python 3.8 and instrument check works fine:

Hey, Thank you for your quick reply... I have a concern that, whether it is possible to use Windows as the host, As when I try to use like that, it is showing OS error while creating then venv. Also if it is possible to share a report or final result of the tool, it will be helpful for me. Looking forward to hearing from you and contribute to this futuristic project.

@sreegopcs Yes, it's possible to use windows as the host. If you setup CakeFuzzer on guest linux, it doesn't touch the host at all (unless you setup development environment with file sharing between host&guest).

Regarding the output. Here is the example output of different stages of Cake Fuzzer:

Here is the instrumentation stripped (It's a long process with a lot of output):

any sugestions

[dawid-czarnecki]

What version of MISP are you trying to scan?

[sreegopcs]

MISP_v2.4.146@0c25b72 is version i am using

[dawid-czarnecki]

You need to set the instrumentation to CAKE version 2 (MISP is built on CAKE 2).
You can do this in config/config.ini. Set the following env var:

INSTRUMENTATION_INI="config/instrumentation_cake2.ini"

i have made the changes in config.ini......but still getting some other error....

Also after successfully completing the execution of all the commands...does the result json contain the vulnerability details pointing towards the exact location of where the error is inside the file?

[dawid-czarnecki]

That's weird error. Do you have the php-parser cloned repo directory? If not try to run this script: cakefuzzer/phpfiles/instrumentation/install_php_parser.sh. If yes than it needs deeper investigation.

You don't get the info about the file that contains the vulnerability but the request that will let you to reproduce it.

[sreegopcs]

I coudn't fix the issue.....PHP parser is their in the repo....and i even tried using the* install_php_parser.sh* command. Still i got the same error... Can u send me the result.json file of MISP and CEREBRATE..if possible both of them, inorder to examine the result and the way of its analysis

Hard to say what's causing the error.
