create an insecure code in python

To create an insecure code in python, you should use functions and methods that are known to be vulnerable. Here are a few examples:

1. Using os.system function to execute shell commands:

main.py
import os 

command = "ls -l"
os.system(command)
49 chars
5 lines

This code is vulnerable to shell injection attacks since the command variable can be manipulated by an attacker to execute arbitrary commands on the system.

2. Using eval to execute arbitrary code:

main.py
input_str = input("Enter a python expression: ")
result = eval(input_str)
74 chars
3 lines

This code is vulnerable to code injection attacks since the input_str variable can be manipulated by an attacker to execute arbitrary code.

3. Using pickle module to deserialize untrusted data:

main.py
import pickle

data = input("Enter pickled data: ")
obj = pickle.loads(data)
77 chars
5 lines

This code is vulnerable to deserialization attacks since the data variable can be manipulated by an attacker to execute arbitrary code on the system.

These are just a few examples of insecure code in python. It is important to always use safe functions and methods and validate user inputs to prevent potential security vulnerabilities.
