Name the function or class in this code that contains a `CWE-209: Generation of Error Message Containing Sensitive Information` vulnerability.
Answer: upload
system: You are an expert security code reviewer. You will be shown a source code file along with a multi-select question listing several CWE (Common Weakness Enumeration) categories. Your task is to identify which of the listed CWEs are present in the code.

OUTPUT FORMAT: Respond with the letter(s) of all correct options, sorted alphabetically and comma-separated, wrapped in a single \boxed{...}. Examples: `\boxed{A}` for one correct, `\boxed{A,C}` for two, `\boxed{A,C,E}` for three. Output the boxed answer ONLY -- no explanation, no other text.

Which of the following CWE vulnerability categories are present in this code? Multiple options may be correct.

  A) CWE-601: URL Redirection to Untrusted Site ('Open Redirect')
  B) CWE-295: Improper Certificate Validation
  C) CWE-1004: Sensitive Cookie Without 'HttpOnly' Flag
  D) CWE-20: Improper Input Validation
  E) CWE-209: Generation of Error Message Containing Sensitive Information
  F) CWE-611: Improper Restriction of XML External Entity Reference
Answer: B
system: You are an expert security code reviewer. You will be shown a source code file along with a multiple-choice question listing several function or class names from that file. Your task is to identify which one contains the specified CWE vulnerability.

OUTPUT FORMAT: Respond with the single letter of the correct option, wrapped in \boxed{...}. Example: `\boxed{B}`. Output the boxed letter ONLY -- no explanation, no other text.

user: ```python
import requests
from requests.auth import HTTPBasicAuth
from dnac_config import DNAC_IP, DNAC_PORT, DNAC_USER, DNAC_PASSWORD
from DNA_Token import get_auth_token
 
def get_devices():
	token = get_auth_token() # Get a Token
	url = "https://10.1.100.10/api/v1/network-device" #Network Device endpoint
	hdr = {'x-auth-token': token, 'content-type' : 'application/json'} #Build header Info
	resp = requests.get(url, verify=False, headers=hdr)  # Make the Get Request
	device_list = resp.json() #capture the data from the controller
	print_device_list(device_list) #pretty print the data we want
    
def print_device_list(device_list):
    for device in device_list['response']:
       
   
    
if __name__ == "__main__":
    get_devices()
```

Which of the following functions or classes contains a `CWE-295: Improper Certificate Validation` vulnerability?

  A) print_device_list
  B) get_devices
Answer: B
system: You are an expert security code reviewer. You will be shown a source code file. Your task is to name the single function or class that contains the specified CWE vulnerability.

OUTPUT FORMAT: Respond with the exact function or class name (no parentheses, no qualifiers, no module prefixes), wrapped in \boxed{...}. Example: `\boxed{salted_hmac}`. Output the boxed name ONLY -- no explanation, no other text.

user: ```python
import requests
from requests.auth import HTTPBasicAuth
from dnac_config import DNAC_IP, DNAC_PORT, DNAC_USER, DNAC_PASSWORD
from DNA_Token import get_auth_token
 
def get_devices():
	token = get_auth_token() # Get a Token
	url = "https://10.1.100.10/api/v1/network-device" #Network Device endpoint
	hdr = {'x-auth-token': token, 'content-type' : 'application/json'} #Build header Info
	resp = requests.get(url, verify=False, headers=hdr)  # Make the Get Request
	device_list = resp.json() #capture the data from the controller
	print_device_list(device_list) #pretty print the data we want
    
def print_device_list(device_list):
    for device in device_list['response']:
       
   
    
if __name__ == "__main__":
    get_devices()
```

Name the function or class in this code that contains a `CWE-295: Improper Certificate Validation` vulnerability.
Answer: get_devices
